+# Hacking Guide for the automatically generated [nbjavac](README.md)
+
+The idea of the new build system is to take the JDK 16+ `javac` sources and
+automatically convert them to run on JDK 8+. As a result the sources come 
+from real JDK repository. The `nbjavac` repository doesn't contain them. 
+This repository only contains the build scripts and
+description of [advanced refactorings](https://netbeans.apache.org/jackpot/HintsFileFormat.html).
+Use:
+
+```bash
+$ JAVA_HOME=/jdk-14/ ant -f ./make/langtools/netbeans/nb-javac jar
+```
+
+to build everything at once. Read below to control individual steps of the build.
+
+
+### Getting the JDK repository
+
+The build requires JDK repository in `jdk` subdirectory of the root of `nb-javac` repository.
+If such directory doesn't exist, the build checks out one:
+
+```bash
+$ JAVA_HOME=/jdk-14/ ant -f ./make/langtools/netbeans/nb-javac init \
+    -Djdk.git.url=https://github.com/openjdk/jdk16 \
+    -Djdk.git.commit=jdk-16+36
+```
+
+If the `jdk` directory is present the build leaves its content untouched. E.g.
+a developer may clone the `jdk` repository manually, switch its content to any other tag,
+make changes in the `jdk/src/java.compiler/` or `jdk/src/jdk.compiler/` directories,
+etc. Bugfixes, features and other changes to `javac` sources are supposed to be done 
+in the `jdk` subdirectory and integrated into the JDK's `javac` official repository.
+
+One can discard any changes by `rm -rf jdk`. Then the subsequent build checks
+a fresh copy of the `jdk` repository from scratch. The default values for
+`jdk.git.url` and `jdk.git.commit` properties are in the
+`./make/langtools/netbeans/nb-javac/nbproject/project.properties`
+file.
+
+
+### Automatically processing the sources
+
+Once the JDK's `javac` sources are in the `jdk` subdirectory, it is necessary
+to apply [advanced refactorings](./make/langtools/netbeans/nb-javac/src/META-INF/upgrade/nbjavac.hint)
+to them. This is done by executing the [jackpot](https://netbeans.apache.org/jackpot/HintsFileFormat.html)
+target:
+
+```bash
+$ JAVA_HOME=/jdk-14/ ant -f ./make/langtools/netbeans/nb-javac jackpot
+```
+
+This step copies the `javac` sources from the `jdk` subdirectory into a sibling
+`src` subdirectory and applies necessary transformations to them.
+The goal of such transformations is to eliminate usage of JDK9+ APIs
+and replace them with JDK8 only APIs.
+
+The sources under the `src/java.compiler` and `src/jdk.compiler` shall not
+be edited manually. Rather than that edit the sources in the original
+`jdk/src/java.compiler/` and `jdk/src/jdk.compiler/` directories. To apply
+the refactorings again execute:
+
+```bash
+$ JAVA_HOME=/jdk-14/ ant -f ./make/langtools/netbeans/nb-javac clean jackpot
+```
+
+### The build
+
+As described in [general documentation](README.md) use the following command to
+generate the final JAR files:
+
+```bash
+$ JAVA_HOME=/jdk-14/ ant -f ./make/langtools/netbeans/nb-javac clean jar
+```
+
+JARs `nb-javac-*-api.jar` and `nb-javac-*-impl.jar` are going to appear
+at location `./make/langtools/netbeans/nb-javac/dist/`.
+
+### Debug & Develop 
+
+Open the `nb-javac` project in NetBeans IDE with
+
+```bash
+$ netbeans --open make/langtools/netbeans/nb-javac/
+```
+
+and you should be able to debug a test (for example `StringWrapperTest`) with following command line:
+
+```bash
+$ JAVA_HOME=/jdk-8/ ant -f make/langtools/netbeans/nb-javac test \
+    -Dincludes=**/StringWrapperTest* \
+    -Ddebug.jvmargs=-agentlib:jdwp=transport=dt_socket,server=y,address=5005,suspend=y
+```
+
+Connect the NetBeans IDE to port 5005 and step through the `nb-javac`
+generated code.

-/**
- * This interface supports the creation of new files by an annotation
- * processor.  Files created in this way will be known to the
- * annotation processing tool implementing this interface, better
- * enabling the tool to manage them.  Source and class files so
- * created will be {@linkplain RoundEnvironment#getRootElements
- * considered for processing} by the tool in a subsequent {@linkplain
- * RoundEnvironment round of processing} after the {@code close}
- * method has been called on the {@code Writer} or {@code
- * OutputStream} used to write the contents of the file.
- *
- * Three kinds of files are distinguished: source files, class files,
- * and auxiliary resource files.
- *
- * <p> There are two distinguished supported locations (subtrees
- * within the logical file system) where newly created files are
- * placed: one for {@linkplain
- * javax.tools.StandardLocation#SOURCE_OUTPUT new source files}, and
- * one for {@linkplain javax.tools.StandardLocation#CLASS_OUTPUT new
- * class files}.  (These might be specified on a tool's command line,
- * for example, using flags such as {@code -s} and {@code -d}.)  The
- * actual locations for new source files and new class files may or
- * may not be distinct on a particular run of the tool.  Resource
- * files may be created in either location.  The methods for reading
- * and writing resources take a relative name argument.  A relative
- * name is a non-null, non-empty sequence of path segments separated
- * by {@code '/'}; {@code '.'} and {@code '..'} are invalid path
- * segments.  A valid relative name must match the
- * &quot;path-rootless&quot; rule of <a
- * href="http://www.ietf.org/rfc/rfc3986.txt">RFC&nbsp;3986</a>, section
- * 3.3.
- *
- * <p>The file creation methods take a variable number of arguments to
- * allow the <em>originating elements</em> to be provided as hints to
- * the tool infrastructure to better manage dependencies.  The
- * originating elements are the types or packages (representing {@code
- * package-info} files) or modules (representing {@code
- * module-info} files) which caused an annotation processor to
- * attempt to create a new file.  For example, if an annotation
- * processor tries to create a source file, {@code
- * GeneratedFromUserSource}, in response to processing
- *
- * <blockquote><pre>
- *  &#64;Generate
- *  public class UserSource {}
- * </pre></blockquote>
- *
- * the type element for {@code UserSource} should be passed as part of
- * the creation method call as in:
- *
- * <blockquote><pre>
- *      filer.createSourceFile("GeneratedFromUserSource",
- *                             eltUtils.getTypeElement("UserSource"));
- * </pre></blockquote>
- *
- * If there are no originating elements, none need to be passed.  This
- * information may be used in an incremental environment to determine
- * the need to rerun processors or remove generated files.
- * Non-incremental environments may ignore the originating element
- * information.
- *
- * <p> During each run of an annotation processing tool, a file with a
- * given pathname may be created only once.  If that file already
- * exists before the first attempt to create it, the old contents will
- * be deleted.  Any subsequent attempt to create the same file during
- * a run will throw a {@link FilerException}, as will attempting to
- * create both a class file and source file for the same type name or
- * same package name.  The {@linkplain Processor initial inputs} to
- * the tool are considered to be created by the zeroth round;
- * therefore, attempting to create a source or class file
- * corresponding to one of those inputs will result in a {@link
- * FilerException}.
- *
- * <p> In general, processors must not knowingly attempt to overwrite
- * existing files that were not generated by some processor.  A {@code
- * Filer} may reject attempts to open a file corresponding to an
- * existing type, like {@code java.lang.Object}.  Likewise, the
- * invoker of the annotation processing tool must not knowingly
- * configure the tool such that the discovered processors will attempt
- * to overwrite existing files that were not generated.
- *
- * <p> Processors can indicate a source or class file is generated by
- * including a {@link javax.annotation.processing.Generated} annotation if the
- * environment is configured so that that type is accessible.
- *
- * @apiNote Some of the effect of overwriting a file can be
- * achieved by using a <i>decorator</i>-style pattern.  Instead of
- * modifying a class directly, the class is designed so that either
- * its superclass is generated by annotation processing or subclasses
- * of the class are generated by annotation processing.  If the
- * subclasses are generated, the parent class may be designed to use
- * factories instead of public constructors so that only subclass
- * instances would be presented to clients of the parent class.

-/**
- * The interface for an annotation processor.
- *
- * <p>Annotation processing happens in a sequence of {@linkplain
- * javax.annotation.processing.RoundEnvironment rounds}.  On each
- * round, a processor may be asked to {@linkplain #process process} a
- * subset of the annotations found on the source and class files
- * produced by a prior round.  The inputs to the first round of
- * processing are the initial inputs to a run of the tool; these
- * initial inputs can be regarded as the output of a virtual zeroth
- * round of processing.  If a processor was asked to process on a
- * given round, it will be asked to process on subsequent rounds,
- * including the last round, even if there are no annotations for it
- * to process.  The tool infrastructure may also ask a processor to
- * process files generated implicitly by the tool's operation.
- *
- * <p> Each implementation of a {@code Processor} must provide a
- * public no-argument constructor to be used by tools to instantiate
- * the processor.  The tool infrastructure will interact with classes
- * implementing this interface as follows:
- *
- * <ol>
- *
- * <li>If an existing {@code Processor} object is not being used, to
- * create an instance of a processor the tool calls the no-arg
- * constructor of the processor class.
- *
- * <li>Next, the tool calls the {@link #init init} method with
- * an appropriate {@link ProcessingEnvironment}.
- *
- * <li>Afterwards, the tool calls {@link #getSupportedAnnotationTypes
- * getSupportedAnnotationTypes}, {@link #getSupportedOptions
- * getSupportedOptions}, and {@link #getSupportedSourceVersion
- * getSupportedSourceVersion}.  These methods are only called once per
- * run, not on each round.
- *
- * <li>As appropriate, the tool calls the {@link #process process}
- * method on the {@code Processor} object; a new {@code Processor}
- * object is <em>not</em> created for each round.
- *
- * </ol>
- *
- * If a processor object is created and used without the above
- * protocol being followed, then the processor's behavior is not
- * defined by this interface specification.
- *
- * <p> The tool uses a <i>discovery process</i> to find annotation
- * processors and decide whether or not they should be run.  By
- * configuring the tool, the set of potential processors can be
- * controlled.  For example, for a {@link javax.tools.JavaCompiler
- * JavaCompiler} the list of candidate processors to run can be
- * {@linkplain javax.tools.JavaCompiler.CompilationTask#setProcessors
- * set directly} or controlled by a {@linkplain
- * javax.tools.StandardLocation#ANNOTATION_PROCESSOR_PATH search path}
- * used for a {@linkplain java.util.ServiceLoader service-style}
- * lookup.  Other tool implementations may have different
- * configuration mechanisms, such as command line options; for
- * details, refer to the particular tool's documentation.  Which
- * processors the tool asks to {@linkplain #process run} is a function
- * of the types of the annotations <em>{@linkplain AnnotatedConstruct present}</em>
- * on the {@linkplain
- * RoundEnvironment#getRootElements root elements}, what {@linkplain
- * #getSupportedAnnotationTypes annotation types a processor
- * supports}, and whether or not a processor {@linkplain #process
- * claims the annotation types it processes}.  A processor will be asked to
- * process a subset of the annotation types it supports, possibly an
- * empty set.
- *
- * For a given round, the tool computes the set of annotation types
- * that are present on the elements enclosed within the root elements.
- * If there is at least one annotation type present, then as
- * processors claim annotation types, they are removed from the set of
- * unmatched annotation types.  When the set is empty or no more
- * processors are available, the round has run to completion.  If
- * there are no annotation types present, annotation processing still
- * occurs but only <i>universal processors</i> which support
- * processing all annotation types, {@code "*"}, can claim the (empty)
- * set of annotation types.
- *
- * <p>An annotation type is considered present if there is at least
- * one annotation of that type present on an element enclosed within
- * the root elements of a round. For this purpose, a type parameter is
- * considered to be enclosed by its {@linkplain
- * TypeParameterElement#getGenericElement generic
- * element}.
-
- * For this purpose, a package element is <em>not</em> considered to
- * enclose the top-level types within that package. (A root element
- * representing a package is created when a {@code package-info} file
- * is processed.) Likewise, for this purpose, a module element is
- * <em>not</em> considered to enclose the packages within that
- * module. (A root element representing a module is created when a
- * {@code module-info} file is processed.)
- *
- * Annotations on {@linkplain
- * java.lang.annotation.ElementType#TYPE_USE type uses}, as opposed to
- * annotations on elements, are ignored when computing whether or not
- * an annotation type is present.
- *
- * <p>An annotation is <em>present</em> if it meets the definition of being
- * present given in {@link AnnotatedConstruct}. In brief, an
- * annotation is considered present for the purposes of discovery if
- * it is directly present or present via inheritance. An annotation is
- * <em>not</em> considered present by virtue of being wrapped by a
- * container annotation. Operationally, this is equivalent to an
- * annotation being present on an element if and only if it would be
- * included in the results of {@link
- * Elements#getAllAnnotationMirrors(Element)} called on that element. Since
- * annotations inside container annotations are not considered
- * present, to properly process {@linkplain
- * java.lang.annotation.Repeatable repeatable annotation types},
- * processors are advised to include both the repeatable annotation
- * type and its containing annotation type in the set of {@linkplain
- * #getSupportedAnnotationTypes() supported annotation types} of a
- * processor.
- *
- * <p>Note that if a processor supports {@code "*"} and returns {@code
- * true}, all annotations are claimed.  Therefore, a universal
- * processor being used to, for example, implement additional validity
- * checks should return {@code false} so as to not prevent other such
- * checkers from being able to run.
- *
- * <p>If a processor throws an uncaught exception, the tool may cease
- * other active annotation processors.  If a processor raises an
- * error, the current round will run to completion and the subsequent
- * round will indicate an {@linkplain RoundEnvironment#errorRaised
- * error was raised}.  Since annotation processors are run in a
- * cooperative environment, a processor should throw an uncaught
- * exception only in situations where no error recovery or reporting
- * is feasible.
- *
- * <p>The tool environment is not required to support annotation
- * processors that access environmental resources, either {@linkplain
- * RoundEnvironment per round} or {@linkplain ProcessingEnvironment
- * cross-round}, in a multi-threaded fashion.
- *
- * <p>If the methods that return configuration information about the
- * annotation processor return {@code null}, return other invalid
- * input, or throw an exception, the tool infrastructure must treat
- * this as an error condition.
- *
- * <p>To be robust when running in different tool implementations, an
- * annotation processor should have the following properties:
- *
- * <ol>
- *
- * <li>The result of processing a given input is not a function of the presence or absence
- * of other inputs (orthogonality).
- *
- * <li>Processing the same input produces the same output (consistency).
- *
- * <li>Processing input <i>A</i> followed by processing input <i>B</i>
- * is equivalent to processing <i>B</i> then <i>A</i>
- * (commutativity)
- *
- * <li>Processing an input does not rely on the presence of the output
- * of other annotation processors (independence)
- *
- * </ol>

-    * describing why there are no completions.
-    *
-    * <p>Completions are informative and may reflect additional

-    *
-    * <blockquote>

-    *    int value();
-    * }

-    * </blockquote>
-    *
-    * (A Mersenne prime is prime number of the form
-    * 2<sup><i>n</i></sup> - 1.) Given an {@code AnnotationMirror}
-    * for this annotation type, a list of all such primes in the
-    * {@code int} range could be returned without examining any other
-    * arguments to {@code getCompletions}:
-    *
-    * <blockquote>
-    * <pre>
-    * import static javax.annotation.processing.Completions.*;
-    * ...
-    * return Arrays.asList({@link Completions#of(String) of}(&quot;3&quot;),
-    *                      of(&quot;7&quot;),

-    * </pre>
-    * </blockquote>
-    *
-    * A more informative set of completions would include the number
-    * of each prime:
-    *
-    * <blockquote>
-    * <pre>
-    * return Arrays.asList({@link Completions#of(String, String) of}(&quot;3&quot;,          &quot;M2&quot;),
-    *                      of(&quot;7&quot;,          &quot;M3&quot;),
-    *                      of(&quot;31&quot;,         &quot;M5&quot;),
-    *                      of(&quot;127&quot;,        &quot;M7&quot;),
-    *                      of(&quot;8191&quot;,       &quot;M13&quot;),

-    * </pre>
-    * </blockquote>
-    *
-    * However, if the {@code userText} is available, it can be checked
-    * to see if only a subset of the Mersenne primes are valid.  For
-    * example, if the user has typed
-    *
-    * <blockquote>
-    * <code>
-    * &#064;MersennePrime(1
-    * </code>
-    * </blockquote>
-    *
-    * the value of {@code userText} will be {@code "1"}; and only
-    * two of the primes are possible completions:
-    *
-    * <blockquote>
-    * <pre>
-    * return Arrays.asList(of(&quot;127&quot;,        &quot;M7&quot;),
-    *                      of(&quot;131071&quot;,     &quot;M17&quot;));
-    * </pre>
-    * </blockquote>
-    *
-    * Sometimes no valid completion is possible.  For example, there
-    * is no in-range Mersenne prime starting with 9:
-    *
-    * <blockquote>
-    * <code>
-    * &#064;MersennePrime(9
-    * </code>
-    * </blockquote>
-    *
-    * An appropriate response in this case is to either return an
-    * empty list of completions,
-    *
-    * <blockquote>
-    * <pre>
-    * return Collections.emptyList();
-    * </pre>
-    * </blockquote>
-    *
-    * or a single empty completion with a helpful message
-    *
-    * <blockquote>
-    * <pre>
-    * return Arrays.asList(of(&quot;&quot;, &quot;No in-range Mersenne primes start with 9&quot;));

-/**
- * Represents a construct that can be annotated.
- *
- * A construct is either an {@linkplain
- * javax.lang.model.element.Element element} or a {@linkplain
- * javax.lang.model.type.TypeMirror type}.  Annotations on an element
- * are on a <em>declaration</em>, whereas annotations on a type are on
- * a specific <em>use</em> of a type name.
- *
- * As defined by <cite>The Java Language Specification</cite>
- * section {@jls 9.7.4}, an annotation on an element is a
- * <em>declaration annotation</em> and an annotation on a type is a
- * <em>type annotation</em>.
- *
- * The terms <em>directly present</em>, <em>present</em>,
- * <em>indirectly present</em>, and <em>associated </em> are used
- * throughout this interface to describe precisely which annotations,
- * either declaration annotations or type annotations, are returned by
- * the methods in this interface.
- *
- * <p>In the definitions below, an annotation <i>A</i> has an
- * annotation type <i>AT</i>. If <i>AT</i> is a repeatable annotation
- * type, the type of the containing annotation is <i>ATC</i>.
- *
- * <p>Annotation <i>A</i> is <em>directly present</em> on a construct
- * <i>C</i> if either:
- *
- * <ul>
- *
- * <li><i>A</i> is {@linkplain
- * javax.lang.model.util.Elements#getOrigin(AnnotatedConstruct,
- * AnnotationMirror) explicitly or implicitly}
- * declared as applying to
- * the source code representation of <i>C</i>.
- *
- * <p>Typically, if exactly one annotation of type <i>AT</i> appears in
- * the source code of representation of <i>C</i>, then <i>A</i> is
- * explicitly declared as applying to <i>C</i>.
- *
- * An annotation of type <i>AT</i> on a {@linkplain
- * RecordComponentElement record component} can be implicitly propagated
- * down to affiliated mandated members. Type annotations modifying the
- * type of a record component can be also propagated to mandated
- * members. Propagation of the annotations to mandated members is
- * governed by rules given in the <cite>The Java Language
- * Specification</cite>.
- *
- * If there are multiple annotations of type <i>AT</i> present on
- * <i>C</i>, then if <i>AT</i> is repeatable annotation type, an
- * annotation of type <i>ATC</i> is {@linkplain javax.lang.model.util.Elements#getOrigin(AnnotatedConstruct, AnnotationMirror) implicitly declared} on <i>C</i>.
- * <li> A representation of <i>A</i> appears in the executable output
- * for <i>C</i>, such as the {@code RuntimeVisibleAnnotations} or
- * {@code RuntimeVisibleParameterAnnotations} attributes of a class
- * file.
- *
- * </ul>
- *
- * <p>An annotation <i>A</i> is <em>present</em> on a
- * construct <i>C</i> if either:
- * <ul>
- *
- * <li><i>A</i> is directly present on <i>C</i>.
- *
- * <li>No annotation of type <i>AT</i> is directly present on
- * <i>C</i>, and <i>C</i> is a class and <i>AT</i> is inheritable
- * and <i>A</i> is present on the superclass of <i>C</i>.
- *
- * </ul>
- *
- * An annotation <i>A</i> is <em>indirectly present</em> on a construct
- * <i>C</i> if both:
- *
- * <ul>
- *
- * <li><i>AT</i> is a repeatable annotation type with a containing
- * annotation type <i>ATC</i>.
- *
- * <li>An annotation of type <i>ATC</i> is directly present on
- * <i>C</i> and <i>A</i> is an annotation included in the result of
- * calling the {@code value} method of the directly present annotation
- * of type <i>ATC</i>.
- *
- * </ul>
- *
- * An annotation <i>A</i> is <em>associated</em> with a construct
- * <i>C</i> if either:
- *
- * <ul>
- *
- * <li> <i>A</i> is directly or indirectly present on <i>C</i>.
- *
- * <li> No annotation of type <i>AT</i> is directly or indirectly
- * present on <i>C</i>, and <i>C</i> is a class, and <i>AT</i> is

-/**
- * A visitor of the values of annotation type elements, using a
- * variant of the visitor design pattern.  Unlike a standard visitor
- * which dispatches based on the concrete type of a member of a type
- * hierarchy, this visitor dispatches based on the type of data
- * stored; there are no distinct subclasses for storing, for example,
- * {@code boolean} values versus {@code int} values.  Classes
- * implementing this interface are used to operate on a value when the
- * type of that value is unknown at compile time.  When a visitor is
- * passed to a value's {@link AnnotationValue#accept accept} method,
- * the <code>visit<i>Xyz</i></code> method applicable to that value is
- * invoked.
- *
- * <p> Classes implementing this interface may or may not throw a
- * {@code NullPointerException} if the additional parameter {@code p}
- * is {@code null}; see documentation of the implementing class for
- * details.
- *
- * @apiNote
- * <strong>WARNING:</strong> It is possible that methods will be added
- * to this interface to accommodate new, currently unknown, language
- * structures added to future versions of the Java programming
- * language.
- *
- * Such additions have already occurred in another visitor interface in
- * this package to support language features added after this API was
- * introduced.
- *
- * Visitor classes directly implementing this interface may be source
- * incompatible with future versions of the platform.  To avoid this
- * source incompatibility, visitor implementations are encouraged to
- * instead extend the appropriate abstract visitor class that
- * implements this interface.  However, an API should generally use
- * this visitor interface as the type for parameters, return type,
- * etc. rather than one of the abstract classes.
- *
- * <p>Methods to accommodate new language constructs are expected to
- * be added as default methods to provide strong source compatibility,
- * as done for {@link ElementVisitor#visitModule visitModule} in
- * {@code ElementVisitor}. The implementations of the default methods
- * in this interface will in turn call {@link visitUnknown
- * visitUnknown}, behavior that will be overridden in concrete
- * visitors supporting the source version with the new language
- * construct.
- *
- * <p>There are several families of classes implementing this visitor
- * interface in the {@linkplain javax.lang.model.util util
- * package}. The families follow a naming pattern along the lines of
- * {@code FooVisitor}<i>N</i> where <i>N</i> indicates the
- * {@linkplain javax.lang.model.SourceVersion source version} the
- * visitor is appropriate for.
- *
- * In particular, a {@code FooVisitor}<i>N</i> is expected to handle
- * all language constructs present in source version <i>N</i>. If
- * there are no new language constructs added in version
- * <i>N</i>&nbsp;+&nbsp;1 (or subsequent releases), {@code
- * FooVisitor}<i>N</i> may also handle that later source version; in
- * that case, the {@link
- * javax.annotation.processing.SupportedSourceVersion
- * SupportedSourceVersion} annotation on the {@code
- * FooVisitor}<i>N</i> class will indicate a later version.
- *
- * When visiting an annotation value representing a language construct
- * introduced <strong>after</strong> source version <i>N</i>, a {@code
- * FooVisitor}<i>N</i> will throw an {@link
- * UnknownAnnotationValueException} unless that behavior is overridden.
- *
- * <p>When choosing which member of a visitor family to subclass,
- * subclassing the most recent one increases the range of source
- * versions covered. When choosing which visitor family to subclass,
- * consider their built-in capabilities:
- *
- * <ul>
- *
- * <li>{@link AbstractAnnotationValueVisitor6
- * AbstractAnnotationValueVisitor}s: Skeletal visitor implementations.
- *
- * <li>{@link SimpleAnnotationValueVisitor6
- * SimpleAnnotationValueVisitor}s: Support default actions and a
- * default return value.
- *
- * </ul>
- *
- * @param <R> the return type of this visitor's methods
- * @param <P> the type of the additional parameter to this visitor's methods.

-import javax.lang.model.util.*;
-
-/**
- * A visitor of program elements, in the style of the visitor design
- * pattern.  Classes implementing this interface are used to operate
- * on an element when the kind of element is unknown at compile time.
- * When a visitor is passed to an element's {@link Element#accept
- * accept} method, the <code>visit<i>Xyz</i></code> method most applicable
- * to that element is invoked.
- *
- * <p> Classes implementing this interface may or may not throw a
- * {@code NullPointerException} if the additional parameter {@code p}
- * is {@code null}; see documentation of the implementing class for
- * details.
- *
- * @apiNote
- * <strong>WARNING:</strong> It is possible that methods will be added
- * to this interface to accommodate new, currently unknown, language
- * structures added to future versions of the Java programming
- * language.
- *
- * Such additions have already occurred to support language features
- * added after this API was introduced.
- *
- * Visitor classes directly implementing this interface may be source
- * incompatible with future versions of the platform.  To avoid this
- * source incompatibility, visitor implementations are encouraged to
- * instead extend the appropriate abstract visitor class that
- * implements this interface.  However, an API should generally use
- * this visitor interface as the type for parameters, return type,
- * etc. rather than one of the abstract classes.
- *
- * <p>Methods to accommodate new language constructs are expected to
- * be added as default methods to provide strong source compatibility,
- * as done for {@link visitModule visitModule}. The implementations of
- * the default methods will in turn call {@link visitUnknown
- * visitUnknown}, behavior that will be overridden in concrete
- * visitors supporting the source version with the new language
- * construct.
- *
- * <p>There are several families of classes implementing this visitor
- * interface in the {@linkplain javax.lang.model.util util
- * package}. The families follow a naming pattern along the lines of
- * {@code FooVisitor}<i>N</i> where <i>N</i> indicates the
- * {@linkplain javax.lang.model.SourceVersion source version} the
- * visitor is appropriate for.
- *
- * In particular, a {@code FooVisitor}<i>N</i> is expected to handle
- * all language constructs present in source version <i>N</i>. If
- * there are no new language constructs added in version
- * <i>N</i>&nbsp;+&nbsp;1 (or subsequent releases), {@code
- * FooVisitor}<i>N</i> may also handle that later source version; in
- * that case, the {@link
- * javax.annotation.processing.SupportedSourceVersion
- * SupportedSourceVersion} annotation on the {@code
- * FooVisitor}<i>N</i> class will indicate a later version.
- *
- * When visiting an element representing a language construct
- * introduced <strong>after</strong> source version <i>N</i>, a {@code
- * FooVisitor}<i>N</i> will throw an {@link UnknownElementException}
- * unless that behavior is overridden.
- *
- * <p>When choosing which member of a visitor family to subclass,
- * subclassing the most recent one increases the range of source
- * versions covered. When choosing which visitor family to subclass,
- * consider their built-in capabilities:
- *
- * <ul>
- *
- * <li>{@link AbstractElementVisitor6 AbstractElementVisitor}s:
- * Skeletal visitor implementations.
- *
- * <li>{@link SimpleElementVisitor6 SimpleElementVisitor}s: Support
- * default actions and a default return value.
- *
- * <li>{@link ElementKindVisitor6 ElementKindVisitor}s: Visit methods
- * provided on a {@linkplain Element#getKind per-kind} granularity as
- * some categories of elements can have more than one kind.
- *
- * <li>{@link ElementScanner6 ElementScanner}s: Scanners are visitors
- * which traverse an element and the elements {@linkplain
- * Element#getEnclosedElements enclosed} by it and associated with it.
- *
- * </ul>
- *
- * @param <R> the return type of this visitor's methods.  Use {@link
- *            Void} for visitors that do not need to return results.
- * @param <P> the type of the additional parameter to this visitor's
- *            methods.  Use {@code Void} for visitors that do not need an
- *            additional parameter.

- * to information about the type and its members.  Note that an enum
- * type and a record type are kinds of classes and an annotation type is a kind of
- * interface.
- *
- * <p> While a {@code TypeElement} represents a class or interface
- * <i>element</i>, a {@link DeclaredType} represents a class
- * or interface <i>type</i>, the latter being a use
- * (or <i>invocation</i>) of the former.
- * The distinction is most apparent with generic types,
- * for which a single element can define a whole
- * family of types.  For example, the element
- * {@code java.util.Set} corresponds to the parameterized types
- * {@code java.util.Set<String>} and {@code java.util.Set<Number>}
- * (and many others), and to the raw type {@code java.util.Set}.
- *
- * <p> Each method of this interface that returns a list of elements
- * will return them in the order that is natural for the underlying
- * source of program information.  For example, if the underlying
- * source of information is Java source code, then the elements will be
- * returned in source code order.

-/**
- * Interfaces used to model elements of the Java programming language.
- *
- * The term "element" in this package is used to refer to program
- * elements, the declared entities that make up a program.  Elements
- * include classes, interfaces, methods, constructors, and fields.
- * The interfaces in this package do not model the structure of a
- * program inside a method body; for example there is no
- * representation of a {@code for} loop or {@code try}-{@code finally}
- * block.  However, the interfaces can model some structures only
- * appearing inside method bodies, such as local variables and
- * anonymous classes.
- *
- * <p>When used in the context of annotation processing, an accurate
- * model of the element being represented must be returned.  As this
- * is a language model, the source code provides the fiducial
- * (reference) representation of the construct in question rather than
- * a representation in an executable output like a class file.
- * Executable output may serve as the basis for creating a modeling
- * element.  However, the process of translating source code to
- * executable output may not permit recovering some aspects of the
- * source code representation.  For example, annotations with
- * {@linkplain java.lang.annotation.RetentionPolicy#SOURCE source}
- * {@linkplain java.lang.annotation.Retention retention} cannot be
- * recovered from class files and class files might not be able to
- * provide source position information.
- *
- * Names of parameters may not be recoverable from class files.
- *
- * The {@linkplain javax.lang.model.element.Modifier modifiers} on an
- * element created from a class file may differ in some cases from an
- * element for the same declaration created from a source file
- * including:
- *
- * <ul>
- * <li> {@code strictfp} on a class or interface
- * <li> {@code final} on a parameter
- * <li> {@code protected}, {@code private}, and {@code static} on classes and interfaces
- * </ul>
- *
- * Some elements which are {@linkplain
- * javax.lang.model.util.Elements.Origin#MANDATED mandated} may not be
- * marked as such when created from class files.
- *
- * Additionally, {@linkplain
- * javax.lang.model.util.Elements.Origin#SYNTHETIC synthetic}
- * constructs in a class file, such as accessor methods used in
- * implementing nested classes and {@linkplain
- * javax.lang.model.util.Elements.Origin#isBridge(ExecutableElement)
- * bridge methods} used in implementing covariant returns, are
- * translation artifacts strictly outside of this model. However, when
- * operating on class files, it is helpful be able to operate on such
- * elements, screening them out when appropriate.
- *
- * <p>During annotation processing, operating on incomplete or
- * erroneous programs is necessary; however, there are fewer
- * guarantees about the nature of the resulting model.  If the source
- * code is not syntactically well-formed or has some other
- * irrecoverable error that could not be removed by the generation of
- * new types, a model may or may not be provided as a quality of
- * implementation issue.
- * If a program is syntactically valid but erroneous in some other
- * fashion, any returned model must have no less information than if
- * all the method bodies in the program were replaced by {@code "throw
- * new RuntimeException();"}.  If a program refers to a missing type Xyz,
- * the returned model must contain no less information than if the
- * declaration of type Xyz were assumed to be {@code "class Xyz {}"},
- * {@code "interface Xyz {}"}, {@code "enum Xyz {}"}, {@code
- * "@interface Xyz {}"}, or {@code "record Xyz {}"}. If a program refers to a missing type {@code
- * Xyz<K1, ... ,Kn>}, the returned model must contain no less
- * information than if the declaration of Xyz were assumed to be
- * {@code "class Xyz<T1, ... ,Tn> {}"} or {@code "interface Xyz<T1,
- * ... ,Tn> {}"}
- *
- * <p> Unless otherwise specified in a particular implementation, the
- * collections returned by methods in this package should be expected
- * to be unmodifiable by the caller and unsafe for concurrent access.
- *
- * <p> Unless otherwise specified, methods in this package will throw
- * a {@code NullPointerException} if given a {@code null} argument.

- * Types and hierarchies of packages comprising a {@index "Java language

- *
- * The members of this package and its subpackages are for use in
- * language modeling and language processing tasks and APIs including,
- * but not limited to, the {@linkplain javax.annotation.processing
- * annotation processing} framework.
- *
- * <p> This language model follows a <i>mirror</i>-based design; see

- * In Proc. of the ACM Conf. on Object-Oriented Programming, Systems,
- * Languages and Applications, October 2004.
- * </blockquote>
- *
- * In particular, the model makes a distinction between declared
- * language constructs, like the {@linkplain javax.lang.model.element
- * element} representing {@code java.util.Set}, and the family of
- * {@linkplain javax.lang.model.type types} that may be associated
- * with an element, like the raw type {@code java.util.Set}, {@code
- * java.util.Set<String>}, and {@code java.util.Set<T>}.

-/**
- * A visitor of types, in the style of the
- * visitor design pattern.  Classes implementing this
- * interface are used to operate on a type when the kind of
- * type is unknown at compile time.  When a visitor is passed to a
- * type's {@link TypeMirror#accept accept} method, the <code>visit<i>Xyz</i></code>
- * method most applicable to that type is invoked.
- *
- * <p> Classes implementing this interface may or may not throw a
- * {@code NullPointerException} if the additional parameter {@code p}
- * is {@code null}; see documentation of the implementing class for
- * details.
- *
- * @apiNote
- * <strong>WARNING:</strong> It is possible that methods will be added
- * to this interface to accommodate new, currently unknown, language
- * structures added to future versions of the Java programming
- * language.
- *
- * Such additions have already occurred to support language features
- * added after this API was introduced.
- *
- * Visitor classes directly implementing this interface may be source
- * incompatible with future versions of the platform.  To avoid this
- * source incompatibility, visitor implementations are encouraged to
- * instead extend the appropriate abstract visitor class that
- * implements this interface.  However, an API should generally use
- * this visitor interface as the type for parameters, return type,
- * etc. rather than one of the abstract classes.
- *
- * <p>Methods to accommodate new language constructs are expected to
- * be added as default methods to provide strong source
- * compatibility. The implementations of the default methods will in
- * turn call {@link visitUnknown visitUnknown}, behavior that will be
- * overridden in concrete visitors supporting the source version with
- * the new language construct.
- *
- * <p>There are several families of classes implementing this visitor
- * interface in the {@linkplain javax.lang.model.util util
- * package}. The families follow a naming pattern along the lines of
- * {@code FooVisitor}<i>N</i> where <i>N</i> indicates the
- * {@linkplain javax.lang.model.SourceVersion source version} the
- * visitor is appropriate for.
- *
- * In particular, a {@code FooVisitor}<i>N</i> is expected to handle
- * all language constructs present in source version <i>N</i>. If
- * there are no new language constructs added in version
- * <i>N</i>&nbsp;+&nbsp;1 (or subsequent releases), {@code
- * FooVisitor}<i>N</i> may also handle that later source version; in
- * that case, the {@link
- * javax.annotation.processing.SupportedSourceVersion
- * SupportedSourceVersion} annotation on the {@code
- * FooVisitor}<i>N</i> class will indicate a later version.
- *
- * When visiting a type representing a language construct
- * introduced <strong>after</strong> source version <i>N</i>, a {@code
- * FooVisitor}<i>N</i> will throw an {@link UnknownTypeException}
- * unless that behavior is overridden.
- *
- * <p>When choosing which member of a visitor family to subclass,
- * subclassing the most recent one increases the range of source
- * versions covered. When choosing which visitor family to subclass,
- * consider their built-in capabilities:
- *
- * <ul>
- *
- * <li>{@link AbstractTypeVisitor6 AbstractTypeVisitor}s:
- * Skeletal visitor implementations.
- *
- * <li>{@link SimpleTypeVisitor6 SimpleTypeVisitor}s: Support
- * default actions and a default return value.
- *
- * <li>{@link TypeKindVisitor6 TypeKindVisitor}s: Visit methods
- * provided on a {@linkplain TypeMirror#getKind per-kind} granularity
- * as some categories of types can have more than one kind.
- *
- * </ul>
- *
- * @param <R> the return type of this visitor's methods.  Use {@link
- *            Void} for visitors that do not need to return results.
- * @param <P> the type of the additional parameter to this visitor's
- *            methods.  Use {@code Void} for visitors that do not need an
- *            additional parameter.

- *
- * The <code>visit<i>Xyz</i></code> methods in this
- * class scan their component elements by calling {@code scan} on
- * their {@linkplain Element#getEnclosedElements enclosed elements},
- * {@linkplain ExecutableElement#getParameters parameters}, etc., as
- * indicated in the individual method specifications.  A subclass can
- * control the order elements are visited by overriding the
- * <code>visit<i>Xyz</i></code> methods.  Note that clients of a scanner
- * may get the desired behavior be invoking {@code v.scan(e, p)} rather
- * than {@code v.visit(e, p)} on the root objects of interest.
- *
- * <p>When a subclass overrides a <code>visit<i>Xyz</i></code> method, the
- * new method can cause the enclosed elements to be scanned in the
- * default way by calling <code>super.visit<i>Xyz</i></code>.  In this
- * fashion, the concrete visitor can control the ordering of traversal
- * over the component elements with respect to the additional
- * processing; for example, consistently calling
- * <code>super.visit<i>Xyz</i></code> at the start of the overridden
- * methods will yield a preorder traversal, etc.  If the component
- * elements should be traversed in some other order, instead of
- * calling <code>super.visit<i>Xyz</i></code>, an overriding visit method
- * should call {@code scan} with the elements in the desired order.

-/**
- * A scanning visitor of program elements with default behavior
- * appropriate for the {@link SourceVersion#RELEASE_6 RELEASE_6}
- * source version.  The <code>visit<i>Xyz</i></code> methods in this
- * class scan their component elements by calling {@code scan} on
- * their {@linkplain Element#getEnclosedElements enclosed elements},
- * {@linkplain ExecutableElement#getParameters parameters}, etc., as
- * indicated in the individual method specifications.  A subclass can
- * control the order elements are visited by overriding the
- * <code>visit<i>Xyz</i></code> methods.  Note that clients of a scanner
- * may get the desired behavior be invoking {@code v.scan(e, p)} rather
- * than {@code v.visit(e, p)} on the root objects of interest.
- *
- * <p>When a subclass overrides a <code>visit<i>Xyz</i></code> method, the
- * new method can cause the enclosed elements to be scanned in the
- * default way by calling <code>super.visit<i>Xyz</i></code>.  In this
- * fashion, the concrete visitor can control the ordering of traversal
- * over the component elements with respect to the additional
- * processing; for example, consistently calling
- * <code>super.visit<i>Xyz</i></code> at the start of the overridden
- * methods will yield a preorder traversal, etc.  If the component
- * elements should be traversed in some other order, instead of
- * calling <code>super.visit<i>Xyz</i></code>, an overriding visit method
- * should call {@code scan} with the elements in the desired order.
- *
- * @apiNote
- * Methods in this class may be overridden subject to their general
- * contract.
- *
- * <p id=note_for_subclasses><strong>WARNING:</strong> The {@code ElementVisitor} interface
- * implemented by this class may have methods added to it in the
- * future to accommodate new, currently unknown, language structures
- * added to future versions of the Java programming language.
- * Therefore, methods whose names begin with {@code "visit"} may be
- * added to this class in the future; to avoid incompatibilities,
- * classes which extend this class should not declare any instance
- * methods with names beginning with {@code "visit"}.</p>
- *
- * <p>When such a new visit method is added, the default
- * implementation in this class will be to directly or indirectly call the {@link
- * #visitUnknown visitUnknown} method.  A new element scanner visitor
- * class will also be introduced to correspond to the new language
- * level; this visitor will have different default behavior for the
- * visit method in question.  When a new visitor is introduced,
- * portions of this visitor class may be deprecated, including its constructors.
- *
- * @param <R> the return type of this visitor's methods.  Use {@link
- *            Void} for visitors that do not need to return results.
- * @param <P> the type of the additional parameter to this visitor's
- *            methods.  Use {@code Void} for visitors that do not need an
- *            additional parameter.

-     *
-     * <p> In the simplest and most typical usage, the value of the

-     * directly enclosing {@code overrider} (the possibly-overriding

-     * Object.hashCode}.  We can then ask whether {@code m1} overrides
-     * {@code m2} within the class {@code String} (it does):

-     *
-     * A more interesting case can be illustrated by the following example
-     * in which a method in type {@code A} does not override a
-     * like-named method in type {@code B}:
-     *
-     * <blockquote>
-     * {@code class A { public void m() {} } }<br>

-     * {@code assert ! elements.overrides(m1, m2,
-     *          elements.getTypeElement("A")); }
-     * </blockquote>
-     *
-     * When viewed as a member of a third type {@code C}, however,
-     * the method in {@code A} does override the one in {@code B}:
-     *
-     * <blockquote>
-     * {@code class C extends A implements B {} }<br>
-     * ...<br>
-     * {@code assert elements.overrides(m1, m2,
-     *          elements.getTypeElement("C")); }
-     * </blockquote>
-     *
-     * @param overrider  the first method, possible overrider
-     * @param overridden  the second method, possibly being overridden
-     * @param type   the type of which the first method is a member

- * programming language.  Therefore, methods whose names begin with

- * should not declare any instance methods with names beginning with
- * {@code "visit"}.</p>
- *
- * <p>When such a new visit method is added, the default
- * implementation in this class will be to directly or indirectly call
- * the {@link #visitUnknown visitUnknown} method.  A new simple type
- * visitor class will also be introduced to correspond to the new
- * language level; this visitor will have different default behavior
- * for the visit method in question.  When a new visitor is

- *
- * <p>When such a new visit method is added, the default

- * visitor class will also be introduced to correspond to the new

-/**
- * Interface to invoke Java programming language compilers from
- * programs.
- *
- * <p>The compiler might generate diagnostics during compilation (for
- * example, error messages).  If a diagnostic listener is provided,
- * the diagnostics will be supplied to the listener.  If no listener
- * is provided, the diagnostics will be formatted in an unspecified
- * format and written to the default output, which is {@code
- * System.err} unless otherwise specified.  Even if a diagnostic
- * listener is supplied, some diagnostics might not fit in a {@code
- * Diagnostic} and will be written to the default output.
- *
- * <p>A compiler tool has an associated standard file manager, which
- * is the file manager that is native to the tool (or built-in).  The
- * standard file manager can be obtained by calling {@linkplain
- * #getStandardFileManager getStandardFileManager}.
- *
- * <p>A compiler tool must function with any file manager as long as
- * any additional requirements as detailed in the methods below are
- * met.  If no file manager is provided, the compiler tool will use a
- * standard file manager such as the one returned by {@linkplain
- * #getStandardFileManager getStandardFileManager}.
- *
- * <p>An instance implementing this interface must conform to
- * <cite>The Java Language Specification</cite>
- * and generate class files conforming to
- * <cite>The Java Virtual Machine Specification</cite>.
- * The versions of these
- * specifications are defined in the {@linkplain Tool} interface.
- *
- * Additionally, an instance of this interface supporting {@link
- * javax.lang.model.SourceVersion#RELEASE_6 SourceVersion.RELEASE_6}
- * or higher must also support {@linkplain javax.annotation.processing
- * annotation processing}.
- *
- * <p>The compiler relies on two services: {@linkplain
- * DiagnosticListener diagnostic listener} and {@linkplain
- * JavaFileManager file manager}.  Although most classes and
- * interfaces in this package defines an API for compilers (and
- * tools in general) the interfaces {@linkplain DiagnosticListener},
- * {@linkplain JavaFileManager}, {@linkplain FileObject}, and
- * {@linkplain JavaFileObject} are not intended to be used in
- * applications.  Instead these interfaces are intended to be
- * implemented and used to provide customized services for a
- * compiler and thus defines an SPI for compilers.
- *
- * <p>There are a number of classes and interfaces in this package
- * which are designed to ease the implementation of the SPI to
- * customize the behavior of a compiler:
- *
- * <dl>
- *   <dt>{@link StandardJavaFileManager}</dt>
- *   <dd>
- *
- *     Every compiler which implements this interface provides a
- *     standard file manager for operating on regular {@linkplain
- *     java.io.File files}.  The StandardJavaFileManager interface
- *     defines additional methods for creating file objects from
- *     regular files.
- *
- *     <p>The standard file manager serves two purposes:
- *
- *     <ul>
- *       <li>basic building block for customizing how a compiler reads
- *       and writes files</li>
- *       <li>sharing between multiple compilation tasks</li>
- *     </ul>
- *
- *     <p>Reusing a file manager can potentially reduce overhead of
- *     scanning the file system and reading jar files.  Although there
- *     might be no reduction in overhead, a standard file manager must
- *     work with multiple sequential compilations making the following
- *     example a recommended coding pattern:
- *
- *     <pre>
- *       File[] files1 = ... ; // input for first compilation task
- *       File[] files2 = ... ; // input for second compilation task
- *
- *       JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
- *       StandardJavaFileManager fileManager = compiler.getStandardFileManager(null, null, null);
- *
- *       {@code Iterable<? extends JavaFileObject>} compilationUnits1 =
- *           fileManager.getJavaFileObjectsFromFiles({@linkplain java.util.Arrays#asList Arrays.asList}(files1));
- *       compiler.getTask(null, fileManager, null, null, null, compilationUnits1).call();
- *
- *       {@code Iterable<? extends JavaFileObject>} compilationUnits2 =
- *           fileManager.getJavaFileObjects(files2); // use alternative method
- *       // reuse the same file manager to allow caching of jar files
- *       compiler.getTask(null, fileManager, null, null, null, compilationUnits2).call();
- *
- *       fileManager.close();</pre>
- *
- *   </dd>
- *
- *   <dt>{@link DiagnosticCollector}</dt>
- *   <dd>
- *     Used to collect diagnostics in a list, for example:
- *     <pre>
- *       {@code Iterable<? extends JavaFileObject>} compilationUnits = ...;
- *       JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
- *       {@code DiagnosticCollector<JavaFileObject> diagnostics = new DiagnosticCollector<JavaFileObject>();}
- *       StandardJavaFileManager fileManager = compiler.getStandardFileManager(diagnostics, null, null);
- *       compiler.getTask(null, fileManager, diagnostics, null, null, compilationUnits).call();
- *
- *       for ({@code Diagnostic<? extends JavaFileObject>} diagnostic : diagnostics.getDiagnostics())
- *           System.out.format("Error on line %d in %s%n",
- *                             diagnostic.getLineNumber(),
- *                             diagnostic.getSource().toUri());
- *
- *       fileManager.close();</pre>
- *   </dd>
- *
- *   <dt>
- *     {@link ForwardingJavaFileManager}, {@link ForwardingFileObject}, and
- *     {@link ForwardingJavaFileObject}
- *   </dt>
- *   <dd>
- *
- *     Subclassing is not available for overriding the behavior of a
- *     standard file manager as it is created by calling a method on a
- *     compiler, not by invoking a constructor.  Instead forwarding
- *     (or delegation) should be used.  These classes makes it easy to
- *     forward most calls to a given file manager or file object while
- *     allowing customizing behavior.  For example, consider how to
- *     log all calls to {@linkplain JavaFileManager#flush}:
- *
- *     <pre>
- *       final  Logger logger = ...;
- *       {@code Iterable<? extends JavaFileObject>} compilationUnits = ...;
- *       JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
- *       StandardJavaFileManager stdFileManager = compiler.getStandardFileManager(null, null, null);
- *       JavaFileManager fileManager = new ForwardingJavaFileManager(stdFileManager) {
- *           public void flush() throws IOException {
- *               logger.entering(StandardJavaFileManager.class.getName(), "flush");
- *               super.flush();
- *               logger.exiting(StandardJavaFileManager.class.getName(), "flush");
- *           }
- *       };
- *       compiler.getTask(null, fileManager, null, null, null, compilationUnits).call();</pre>
- *   </dd>
- *
- *   <dt>{@link SimpleJavaFileObject}</dt>
- *   <dd>
- *
- *     This class provides a basic file object implementation which
- *     can be used as building block for creating file objects.  For
- *     example, here is how to define a file object which represent
- *     source code stored in a string:
- *
- *     <pre>
- *       /**
- *        * A file object used to represent source coming from a string.
- *        {@code *}/
- *       public class JavaSourceFromString extends SimpleJavaFileObject {
- *           /**
- *            * The source code of this "file".
- *            {@code *}/
- *           final String code;
- *
- *           /**
- *            * Constructs a new JavaSourceFromString.
- *            * {@code @}param name the name of the compilation unit represented by this file object
- *            * {@code @}param code the source code for the compilation unit represented by this file object
- *            {@code *}/
- *           JavaSourceFromString(String name, String code) {
- *               super({@linkplain java.net.URI#create URI.create}("string:///" + name.replace('.','/') + Kind.SOURCE.extension),
- *                     Kind.SOURCE);
- *               this.code = code;
- *           }
- *
- *           {@code @}Override
- *           public CharSequence getCharContent(boolean ignoreEncodingErrors) {
- *               return code;

-/**
- * File manager for tools operating on Java programming language
- * source and class files.  In this context, <em>file</em> means an
- * abstraction of regular files and other sources of data.
- *
- * <p>When constructing new JavaFileObjects, the file manager must
- * determine where to create them.  For example, if a file manager
- * manages regular files on a file system, it would most likely have a
- * current/working directory to use as default location when creating
- * or finding files.  A number of hints can be provided to a file
- * manager as to where to create files.  Any file manager might choose
- * to ignore these hints.
- *
- * <p>Some methods in this interface use class names.  Such class
- * names must be given in the Java Virtual Machine internal form of
- * fully qualified class and interface names.  For convenience '.'
- * and '/' are interchangeable.  The internal form is defined in
- * chapter four of
- * <cite>The Java Virtual Machine Specification</cite>.
-
- * <blockquote><p>
- *   <i>Discussion:</i> this means that the names
- *   "java/lang.package-info", "java/lang/package-info",
- *   "java.lang.package-info", are valid and equivalent.  Compare to
- *   binary name as defined in
- *   <cite>The Java Language Specification</cite>,
- *   section 13.1 "The Form of a Binary".
- * </p></blockquote>
- *
- * <p>The case of names is significant.  All names should be treated
- * as case-sensitive.  For example, some file systems have
- * case-insensitive, case-aware file names.  File objects representing
- * such files should take care to preserve case by using {@link
- * java.io.File#getCanonicalFile} or similar means.  If the system is
- * not case-aware, file objects must use other means to preserve case.
- *
- * <p><em><a id="relative_name">Relative names</a>:</em> some
- * methods in this interface use relative names.  A relative name is a
- * non-null, non-empty sequence of path segments separated by '/'.
- * '.' or '..'  are invalid path segments.  A valid relative name must
- * match the "path-rootless" rule of <a
- * href="http://www.ietf.org/rfc/rfc3986.txt">RFC&nbsp;3986</a>,
- * section&nbsp;3.3.  Informally, this should be true:
- *
- * <!-- URI.create(relativeName).normalize().getPath().equals(relativeName) -->
- * <pre>  URI.{@linkplain java.net.URI#create create}(relativeName).{@linkplain java.net.URI#normalize() normalize}().{@linkplain java.net.URI#getPath getPath}().equals(relativeName)</pre>
- *
- * <p>All methods in this interface might throw a SecurityException.
- *
- * <p>An object of this interface is not required to support
- * multi-threaded access, that is, be synchronized.  However, it must
- * support concurrent access to different file objects created by this
- * object.
- *
- * <p><em>Implementation note:</em> a consequence of this requirement
- * is that a trivial implementation of output to a {@linkplain
- * java.util.jar.JarOutputStream} is not a sufficient implementation.
- * That is, rather than creating a JavaFileObject that returns the
- * JarOutputStream directly, the contents must be cached until closed
- * and then written to the JarOutputStream.
- *
- * <p>Unless explicitly allowed, all methods in this interface might
- * throw a NullPointerException if given a {@code null} argument.

- *         </blockquote>
- *       </li>
- *     </ul>
- *   </li>

- *     The {@linkplain java.net.URI URI} returned from
- *     <code>{@linkplain FileObject#toUri()}</code>
- *     <ul>
- *       <li>

- *       <li>
- *         must have a {@linkplain java.net.URI#normalize() normalized}
- *         {@linkplain java.net.URI#getPath() path component} which
- *         can be resolved without any process-specific context such
- *         as the current directory (file names must be absolute).
- *       </li>
- *     </ul>
- *   </li>
- * </ul>
- *
- * According to these rules, the following URIs, for example, are
- * allowed:
- * <ul>
- *   <li>
- *     <code>file:///C:/Documents%20and%20Settings/UncleBob/BobsApp/Test.java</code>

- *     <code>jar:///C:/Documents%20and%20Settings/UncleBob/lib/vendorA.jar!/com/vendora/LibraryClass.class</code>
- *   </li>
- * </ul>
- * Whereas these are not (reason in parentheses):
- * <ul>
- *   <li>
- *     <code>file:BobsApp/Test.java</code> (the file name is relative
- *     and depend on the current directory)
- *   </li>
- *   <li>
- *     <code>jar:lib/vendorA.jar!/com/vendora/LibraryClass.class</code>
- *     (the first half of the path depends on the current directory,
- *     whereas the component after ! is legal)
- *   </li>
- *   <li>
- *     <code>Test.java</code> (this URI depends on the current
- *     directory and does not have a schema)
- *   </li>
- *   <li>
- *     <code>jar:///C:/Documents%20and%20Settings/UncleBob/BobsApp/../lib/vendorA.jar!com/vendora/LibraryClass.class</code>
- *     (the path is not normalized)

- * </ul>
- *
- * <p>All implementations of this interface must support Path objects representing
- * files in the {@linkplain java.nio.file.FileSystems#getDefault() default file system.}
- * It is recommended that implementations should support Path objects from any filesystem.</p>
- *
- *
- * @apiNote
- * Some methods on this interface take a {@code Collection<? extends Path>}
- * instead of {@code Iterable<? extends Path>}.
- * This is to prevent the possibility of accidentally calling the method
- * with a single {@code Path} as such an argument, because although
- * {@code Path} implements {@code Iterable<Path>}, it would almost never be

-/**
- * Provides interfaces for tools which can be invoked from a program,
- * for example, compilers.
- *
- * <p>These interfaces and classes are required as part of the
- * Java Platform, Standard Edition (Java SE),
- * but there is no requirement to provide any tools implementing them.
- *
- * <p>Unless explicitly allowed, all methods in this package might
- * throw a {@linkplain java.lang.NullPointerException} if given a
- * {@code null} argument or if given a
- * {@linkplain java.lang.Iterable list or collection} containing
- * {@code null} elements.  Similarly, no method may return
- * {@code null} unless explicitly allowed.
- *
- * <p>This package is the home of the Java programming language compiler framework.  This
- * framework allows clients of the framework to locate and run
- * compilers from programs.  The framework also provides Service
- * Provider Interfaces (SPI) for structured access to diagnostics
- * ({@linkplain javax.tools.DiagnosticListener}) as well as a file
- * abstraction for overriding file access ({@linkplain
- * javax.tools.JavaFileManager} and {@linkplain
- * javax.tools.JavaFileObject}).  See {@linkplain
- * javax.tools.JavaCompiler} for more details on using the SPI.
- *
- * <p>There is no requirement for a compiler at runtime.  However, if
- * a default compiler is provided, it can be located using the
- * {@linkplain javax.tools.ToolProvider}, for example:
- *
- * <p>{@code JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();}
- *
- * <p>It is possible to provide alternative compilers or tools
- * through the {@linkplain java.util.ServiceLoader service provider
- * mechanism}.
- *
- * <p>For example, if {@code com.vendor.VendorJavaCompiler} is a
- * provider of the {@code JavaCompiler} tool then its jar file
- * would contain the file {@code
- * META-INF/services/javax.tools.JavaCompiler}.  This file would
- * contain the single line:
- *
- * <p>{@code com.vendor.VendorJavaCompiler}
- *
- * <p>If the jar file is on the class path, VendorJavaCompiler can be
- * located using code like this:
- *
- * <p>{@code JavaCompiler compiler = ServiceLoader.load(JavaCompiler.class).iterator().next();}

-/**
- * A visitor of trees, in the style of the visitor design pattern.
- * Classes implementing this interface are used to operate
- * on a tree when the kind of tree is unknown at compile time.
- * When a visitor is passed to an tree's {@link Tree#accept
- * accept} method, the <code>visit<i>Xyz</i></code> method most applicable
- * to that tree is invoked.
- *
- * <p> Classes implementing this interface may or may not throw a
- * {@code NullPointerException} if the additional parameter {@code p}
- * is {@code null}; see documentation of the implementing class for
- * details.
- *
- * <p> <b>WARNING:</b> It is possible that methods will be added to
- * this interface to accommodate new, currently unknown, language
- * structures added to future versions of the Java programming
- * language.  Therefore, visitor classes directly implementing this
- * interface may be source incompatible with future versions of the
- * platform.
- *
- * @param <R> the return type of this visitor's methods.  Use {@link
- *            Void} for visitors that do not need to return results.
- * @param <P> the type of the additional parameter to this visitor's
- *            methods.  Use {@code Void} for visitors that do not need an
- *            additional parameter.

-Usage:\n\
-\    doclint [options] source-files...\n\
-\n\
-Options:\n\
-\  -Xmsgs  \n\
-\    Same as -Xmsgs:all\n\
-\  -Xmsgs:values\n\
-\    Specify categories of issues to be checked, where ''values''\n\
-\    is a comma-separated list of any of the following:\n\
-\      reference      show places where comments contain incorrect\n\
-\                     references to Java source code elements\n\
-\      syntax         show basic syntax errors within comments\n\
-\      html           show issues with HTML tags and attributes\n\
-\      accessibility  show issues for accessibility\n\
-\      missing        show issues with missing documentation\n\
-\      all            all of the above\n\
-\    Precede a value with ''-'' to negate it\n\
-\    Categories may be qualified by one of:\n\
-\      /public /protected /package /private\n\
-\    For positive categories (not beginning with ''-'')\n\
-\    the qualifier applies to that access level and above.\n\
-\    For negative categories (beginning with ''-'')\n\
-\    the qualifier applies to that access level and below.\n\
-\    If a qualifier is missing, the category applies to\n\
-\    all access levels.\n\
-\    For example, -Xmsgs:all,-syntax/private\n\
-\    This will enable all messages, except syntax errors\n\
-\    in the doc comments of private methods.\n\
-\    If no -Xmsgs options are provided, the default is\n\
-\    equivalent to -Xmsgs:all/protected, meaning that\n\
-\    all messages are reported for protected and public\n\
-\    declarations only. \n\
-\  -XcheckPackage:<packages>\n\
-\    Enable or disable checks in specific packages.\n\
-\    <packages> is a comma separated list of package specifiers.\n\
-\    Package specifier is either a qualified name of a package\n\
-\    or a package name prefix followed by ''.*'', which expands to\n\
-\    all sub-packages of the given package. Prefix the package specifier\n\
-\    with ''-'' to disable checks for the specified packages.\n\
-\  -stats\n\
-\    Report statistics on the reported issues.\n\
-\  -h -help --help -usage -?\n\
-\    Show this message.\n\
-\n\
-The following javac options are also supported\n\
-\  -bootclasspath, -classpath, -cp, -sourcepath, -Xmaxerrs, -Xmaxwarns\n\
-\n\
-To run doclint on part of a project, put the compiled classes for your\n\
-project on the classpath (or bootclasspath), then specify the source files\n\
-to be checked on the command line.

- *      obvious way, since they are an expected aspect of the method's

- *  <li>Unchecked exceptions which have already been caught and wrapped in
- *      ClientCodeException are left alone to continue propagating upwards.

- *  The intent is that ClientCodeException can be caught at an appropriate point
- *  in the program and can be distinguished from any unanticipated unchecked

-/**
- * A pool of reusable JavacTasks. When a task is no valid anymore, it is returned to the pool,
- * and its Context may be reused for future processing in some cases. The reuse is achieved
- * by replacing some components (most notably JavaCompiler and Log) with reusable counterparts,
- * and by cleaning up leftovers from previous compilation.
- * <p>
- * For each combination of options, a separate task/context is created and kept, as most option
- * values are cached inside components themselves.
- * <p>
- * When the compilation redefines sensitive classes (e.g. classes in the the java.* packages), the
- * task/context is not reused.
- * <p>
- * When the task is reused, then packages that were already listed won't be listed again.
- * <p>
- * Care must be taken to only return tasks that won't be used by the original caller.
- * <p>
- * Care must also be taken when custom components are installed, as those are not cleaned when the
- * task/context is reused, and subsequent getTask may return a task based on a context with these
- * custom components.
- *
- * <p><b>This is NOT part of any supported API.
- * If you write code that depends on this, you do so at your own risk.
- * This code and its internal interfaces are subject to change or
- * deletion without notice.</b>

-/**
- * Container for all annotations (attributes in javac) on a Symbol.
- *
- * This class is explicitly mutable. Its contents will change when attributes
- * are annotated onto the Symbol. However this class depends on the facts that
- * List (in javac) is immutable.
- *
- * An instance of this class can be in one of three states:
- *
- * NOT_STARTED indicates that the Symbol this instance belongs to has not been
- * annotated (yet). Specifically if the declaration is not annotated this
- * instance will never move past NOT_STARTED. You can never go back to
- * NOT_STARTED.
- *
- * IN_PROGRESS annotations have been found on the declaration. Will be processed
- * later. You can reset to IN_PROGRESS. While IN_PROGRESS you can set the list
- * of attributes (and this moves out of the IN_PROGRESS state).
- *
- * "unnamed" this SymbolMetadata contains some attributes, possibly the final set.
- * While in this state you can only prepend or append to the attributes not set
- * it directly. You can also move back to the IN_PROGRESS state using reset().
- *
- * <p><b>This is NOT part of any supported API. If you write code that depends
- * on this, you do so at your own risk. This code and its internal interfaces
- * are subject to change or deletion without notice.</b>

-     * An upwards projection maps a type T into a type S such that (i) T has no variables in V,

-     * Note that projections are only allowed to touch variables in V. Therefore, it is possible for
-     * a projection to leave its input type unchanged if it does not contain any variables in V.
-     *
-     * Moreover, note that while an upwards projection is always defined (every type as an upper bound),
-     * a downwards projection is not always defined.

-/**
- * This class performs attribution of method/constructor arguments when target-typing is enabled
- * (source >= 8); for each argument that is potentially a poly expression, this class builds
- * a rich representation (see {@link ArgumentType} which can then be used for performing fast overload
- * checks without requiring multiple attribution passes over the same code.
- *
- * The attribution strategy for a given method/constructor argument A is as follows:
- *
- * - if A is potentially a poly expression (i.e. diamond instance creation expression), a speculative
- * pass over A is performed; the results of such speculative attribution are then saved in a special
- * type, so that enclosing overload resolution can be carried by simply checking compatibility against the
- * type determined during this speculative pass.
- *
- * - if A is a standalone expression, regular attribution takes place.
- *
- * To minimize the speculative work, a cache is used, so that already computed argument types
- * associated with a given unique source location are never recomputed multiple times.

-         * target METHOD, it is propagated to the accessor and so on. But at the moment when method members are generated
-         * there is no enough information to propagate only the right annotations. So all the annotations are propagated
-         * to all the possible locations.
-         *
-         * At this point we need to remove all the annotations that are not in place before going on with the annotation
-         * party. On top of the above there is the issue that there is no AST representing record components, just symbols
-         * so the corresponding field has been holding all the annotations and it's metadata has been modified as if it
-         * was both a field and a record component.
-         *
-         * So there are two places where we need to trim annotations from: the metadata of the symbol and / or the modifiers
-         * in the AST. Whatever is in the metadata will be written to the class file, whatever is in the modifiers could
-         * be see by annotation processors.
-         *
-         * The metadata contains both type annotations and declaration annotations. At this point of the game we don't
-         * need to care about type annotations, they are all in the right place. But we could need to remove declaration
-         * annotations. So for declaration annotations if they are not applicable to the record member, excluding type
-         * annotations which are already correct, then we will remove it. For the AST modifiers if the annotation is not
-         * applicable either as type annotation and or declaration annotation, only in that case it will be removed.
-         *
-         * So it could be that annotation is removed as a declaration annotation but it is kept in the AST modifier for
-         * further inspection by annotation processors.
-         *
-         * For example:
-         *
-         *     import java.lang.annotation.*;
-         *
-         *     @Target({ElementType.TYPE_USE, ElementType.RECORD_COMPONENT})
-         *     @Retention(RetentionPolicy.RUNTIME)
-         *     @interface Anno { }
-         *
-         *     record R(@Anno String s) {}
-         *
-         * at this point we will have for the case of the generated field:
-         *   - @Anno in the modifier
-         *   - @Anno as a type annotation
-         *   - @Anno as a declaration annotation
-         *
-         * the last one should be removed because the annotation has not FIELD as target but it was applied as a
-         * declaration annotation because the field was being treated both as a field and as a record component
-         * as we have already copied the annotations to the record component, now the field doesn't need to hold
-         * annotations that are not intended for it anymore. Still @Anno has to be kept in the AST's modifiers as it
-         * is applicable as a type annotation to the type of the field.

-/** This class enters symbols for all encountered definitions into
- *  the symbol table. The pass consists of high-level two phases,
- *  organized as follows:
- *
- *  <p>In the first phase, all class symbols are entered into their
- *  enclosing scope, descending recursively down the tree for classes
- *  which are members of other classes. The class symbols are given a
- *  TypeEnter object as completer.
- *
- *  <p>In the second phase classes are completed using
- *  TypeEnter.complete(). Completion might occur on demand, but
- *  any classes that are not completed that way will be eventually
- *  completed by processing the `uncompleted' queue. Completion
- *  entails determination of a class's parameters, supertype and
- *  interfaces, as well as entering all symbols defined in the
- *  class into its scope, with the exception of class symbols which
- *  have been entered in phase 1.
- *
- *  <p>Whereas the first phase is organized as a sweep through all
- *  compiled syntax trees, the second phase is on-demand. Members of a
- *  class are entered when the contents of a class are first
- *  accessed. This is accomplished by installing completer objects in
- *  class symbols for compiled classes which invoke the type-enter
- *  phase for the corresponding class tree.
- *
- *  <p>Classes migrate from one phase to the next via queues:
- *
- *  <pre>{@literal
- *  class enter -> (Enter.uncompleted)         --> type enter
- *              -> (Todo)                      --> attribute
- *                                              (only for toplevel classes)
- *  }</pre>

- *  <p><b>This is NOT part of any supported API.
- *  If you write code that depends on this, you do so at your own risk.

-/** This pass implements dataflow analysis for Java programs though
- *  different AST visitor steps. Liveness analysis (see AliveAnalyzer) checks that
- *  every statement is reachable. Exception analysis (see FlowAnalyzer) ensures that
- *  every checked exception that is thrown is declared or caught.  Definite assignment analysis
- *  (see AssignAnalyzer) ensures that each variable is assigned when used.  Definite
- *  unassignment analysis (see AssignAnalyzer) in ensures that no final variable
- *  is assigned more than once. Finally, local variable capture analysis (see CaptureAnalyzer)
- *  determines that local variables accessed within the scope of an inner class/lambda
- *  are either final or effectively-final.
- *
- *  <p>The JLS has a number of problems in the
- *  specification of these flow analysis problems. This implementation
- *  attempts to address those issues.
- *
- *  <p>First, there is no accommodation for a finally clause that cannot
- *  complete normally. For liveness analysis, an intervening finally
- *  clause can cause a break, continue, or return not to reach its
- *  target.  For exception analysis, an intervening finally clause can
- *  cause any exception to be "caught".  For DA/DU analysis, the finally
- *  clause can prevent a transfer of control from propagating DA/DU
- *  state to the target.  In addition, code in the finally clause can
- *  affect the DA/DU status of variables.
- *
- *  <p>For try statements, we introduce the idea of a variable being
- *  definitely unassigned "everywhere" in a block.  A variable V is
- *  "unassigned everywhere" in a block iff it is unassigned at the
- *  beginning of the block and there is no reachable assignment to V
- *  in the block.  An assignment V=e is reachable iff V is not DA
- *  after e.  Then we can say that V is DU at the beginning of the
- *  catch block iff V is DU everywhere in the try block.  Similarly, V
- *  is DU at the beginning of the finally block iff V is DU everywhere
- *  in the try block and in every catch block.  Specifically, the
- *  following bullet is added to 16.2.2
- *  <pre>
- *      V is <em>unassigned everywhere</em> in a block if it is
- *      unassigned before the block and there is no reachable
- *      assignment to V within the block.
- *  </pre>
- *  <p>In 16.2.15, the third bullet (and all of its sub-bullets) for all
- *  try blocks is changed to
- *  <pre>
- *      V is definitely unassigned before a catch block iff V is
- *      definitely unassigned everywhere in the try block.
- *  </pre>
- *  <p>The last bullet (and all of its sub-bullets) for try blocks that
- *  have a finally block is changed to
- *  <pre>
- *      V is definitely unassigned before the finally block iff
- *      V is definitely unassigned everywhere in the try block
- *      and everywhere in each catch block of the try statement.
- *  </pre>
- *  <p>In addition,
- *  <pre>
- *      V is definitely assigned at the end of a constructor iff
- *      V is definitely assigned after the block that is the body
- *      of the constructor and V is definitely assigned at every
- *      return that can return from the constructor.
- *  </pre>
- *  <p>In addition, each continue statement with the loop as its target
- *  is treated as a jump to the end of the loop body, and "intervening"
- *  finally clauses are treated as follows: V is DA "due to the
- *  continue" iff V is DA before the continue statement or V is DA at
- *  the end of any intervening finally block.  V is DU "due to the
- *  continue" iff any intervening finally cannot complete normally or V
- *  is DU at the end of every intervening finally block.  This "due to
- *  the continue" concept is then used in the spec for the loops.
- *
- *  <p>Similarly, break statements must consider intervening finally
- *  blocks.  For liveness analysis, a break statement for which any
- *  intervening finally cannot complete normally is not considered to
- *  cause the target statement to be able to complete normally. Then
- *  we say V is DA "due to the break" iff V is DA before the break or
- *  V is DA at the end of any intervening finally block.  V is DU "due
- *  to the break" iff any intervening finally cannot complete normally
- *  or V is DU at the break and at the end of every intervening
- *  finally block.  (I suspect this latter condition can be
- *  simplified.)  This "due to the break" is then used in the spec for
- *  all statements that can be "broken".
- *
- *  <p>The return statement is treated similarly.  V is DA "due to a
- *  return statement" iff V is DA before the return statement or V is
- *  DA at the end of any intervening finally block.  Note that we
- *  don't have to worry about the return expression because this
- *  concept is only used for constructors.
- *
- *  <p>There is no spec in the JLS for when a variable is definitely
- *  assigned at the end of a constructor, which is needed for final
- *  fields (8.3.1.2).  We implement the rule that V is DA at the end
- *  of the constructor iff it is DA and the end of the body of the
- *  constructor and V is DA "due to" every return of the constructor.
- *
- *  <p>Intervening finally blocks similarly affect exception analysis.  An
- *  intervening finally that cannot complete normally allows us to ignore
- *  an otherwise uncaught exception.
- *
- *  <p>To implement the semantics of intervening finally clauses, all
- *  nonlocal transfers (break, continue, return, throw, method call that
- *  can throw a checked exception, and a constructor invocation that can
- *  thrown a checked exception) are recorded in a queue, and removed
- *  from the queue when we complete processing the target of the
- *  nonlocal transfer.  This allows us to modify the queue in accordance
- *  with the above rules when we encounter a finally clause.  The only
- *  exception to this [no pun intended] is that checked exceptions that
- *  are known to be caught or declared to be caught in the enclosing
- *  method are not recorded in the queue, but instead are recorded in a
- *  global variable "{@code Set<Type> thrown}" that records the type of all
- *  exceptions that can be thrown.
- *
- *  <p>Other minor issues the treatment of members of other classes
- *  (always considered DA except that within an anonymous class
- *  constructor, where DA status from the enclosing scope is
- *  preserved), treatment of the case expression (V is DA before the
- *  case expression iff V is DA after the switch expression),
- *  treatment of variables declared in a switch block (the implied
- *  DA/DU status after the switch expression is DU and not DA for
- *  variables defined in a switch block), the treatment of boolean ?:
- *  expressions (The JLS rules only handle b and c non-boolean; the
- *  new rule is that if b and c are boolean valued, then V is
- *  (un)assigned after a?b:c when true/false iff V is (un)assigned
- *  after b when true/false and V is (un)assigned after c when
- *  true/false).
- *
- *  <p>There is the remaining question of what syntactic forms constitute a
- *  reference to a variable.  It is conventional to allow this.x on the
- *  left-hand-side to initialize a final instance field named x, yet
- *  this.x isn't considered a "use" when appearing on a right-hand-side
- *  in most implementations.  Should parentheses affect what is
- *  considered a variable reference?  The simplest rule would be to
- *  allow unqualified forms only, parentheses optional, and phase out
- *  support for assigning to a final field via this.x.
- *
- *  <p><b>This is NOT part of any supported API.
- *  If you write code that depends on this, you do so at your own risk.
- *  This code and its internal interfaces are subject to change or
- *  deletion without notice.</b>

-             * switching on the argument string's hash value and
-             * computing a string's position in the list of original
-             * case labels, if any, followed by a second switch on the
-             * computed integer value.  The second switch has the same
-             * code structure as the original string switch statement
-             * except that the string case labels are replaced with
-             * positional integer constants starting at 0.
-             *
-             * The first switch statement can be thought of as an
-             * inlined map from strings to their position in the case
-             * label list.  An alternate implementation would use an
-             * actual Map for this purpose, as done for enum switches.
-             *
-             * With some additional effort, it would be possible to
-             * use a single switch statement on the hash code of the
-             * argument, but care would need to be taken to preserve
-             * the proper control flow in the presence of hash
-             * collisions and other complications, such as
-             * fallthroughs.  Switch statements with one or two
-             * alternatives could also be specially translated into
-             * if-then statements to omit the computation of the hash
-             * code.
-             *
-             * The generated code assumes that the hashing algorithm
-             * of String is the same in the compilation environment as
-             * in the environment the code will run in.  The string
-             * hashing algorithm in the SE JDK has been unchanged
-             * since at least JDK 1.2.  Since the algorithm has been
-             * specified since that release as well, it is very
-             * unlikely to be changed in the future.
-             *
-             * Different hashing algorithms, such as the length of the
-             * strings or a perfect hashing algorithm over the
-             * particular set of case labels, could potentially be
-             * used instead of String.hashCode.

-     * Resolution of member references is typically done as a single

-     * the target functional descriptor.
-     *
-     * If the member reference is a method reference with a type qualifier,
-     * a two-step lookup process is performed. The first step uses the
-     * expected argument list A, while the second step discards the first
-     * type from A (which is treated as a receiver type).
-     *
-     * There are two cases in which inference is performed: (i) if the member
-     * reference is a constructor reference and the qualifier type is raw - in
-     * which case diamond inference is used to infer a parameterization for the
-     * type qualifier; (ii) if the member reference is an unbound reference
-     * where the type qualifier is raw - in that case, during the unbound lookup
-     * the receiver argument type is used to infer an instantiation for the raw
-     * qualifier type.
-     *
-     * When a multi-step resolution process is exploited, the process of picking
-     * the resulting symbol is delegated to an helper class {@link com.sun.tools.javac.comp.Resolve.ReferenceChooser}.
-     *
-     * This routine returns a pair (T,S), where S is the member reference symbol,
-     * and T is the type of the class in which S is defined. This is necessary as
-     * the type T might be dynamically inferred (i.e. if constructor reference
-     * has a raw qualifier).

-/** This is the second phase of Enter, in which classes are completed
- *  by resolving their headers and entering their members in the into
- *  the class scope. See Enter for an overall overview.
- *
- *  This class uses internal phases to process the classes. When a phase
- *  processes classes, the lower phases are not invoked until all classes
- *  pass through the current phase. Note that it is possible that upper phases
- *  are run due to recursive completion. The internal phases are:
- *  - ImportPhase: shallow pass through imports, adds information about imports
- *                 the NamedImportScope and StarImportScope, but avoids queries
- *                 about class hierarchy.
- *  - HierarchyPhase: resolves the supertypes of the given class. Does not handle
- *                    type parameters of the class or type argument of the supertypes.
- *  - HeaderPhase: finishes analysis of the header of the given class by resolving
- *                 type parameters, attributing supertypes including type arguments
- *                 and scheduling full annotation attribution. This phase also adds
- *                 a synthetic default constructor if needed and synthetic "this" field.
- *  - MembersPhase: resolves headers for fields, methods and constructors in the given class.
- *                  Also generates synthetic enum members.
- *
- *  <p><b>This is NOT part of any supported API.
- *  If you write code that depends on this, you do so at your own risk.
- *  This code and its internal interfaces are subject to change or
- *  deletion without notice.</b>

-/**
- *  Implementation of JavaFileObject using java.nio.file API.
- *
- *  <p>PathFileObjects are, for the most part, straightforward wrappers around
- *  immutable absolute Path objects. Different subtypes are used to provide
- *  specialized implementations of "inferBinaryName" and "getName" that capture
- *  additional information available at the time the object is created.
- *
- *  <p>In general, {@link JavaFileManager#isSameFile} should be used to
- *  determine whether two file objects refer to the same file on disk.
- *  PathFileObject also supports the standard {@code equals} and {@code hashCode}
- *  methods, primarily for convenience when working with collections.
- *  All of these operations delegate to the equivalent operations on the
- *  underlying Path object.
- *
- *  <p><b>This is NOT part of any supported API.
- *  If you write code that depends on this, you do so at your own risk.
- *  This code and its internal interfaces are subject to change or
- *  deletion without notice.</b>

-/** A JVM class file.
- *
- *  <p>Generic Java classfiles have one additional attribute for classes,
- *  methods and fields:
- *  <pre>
- *   "Signature" (u4 attr-length, u2 signature-index)
- *  </pre>
- *
- *  <p>A signature gives the full Java type of a method or field. When
- *  used as a class attribute, it indicates type parameters, followed
- *  by supertype, followed by all interfaces.
- *  <pre>
- *     methodOrFieldSignature ::= type
- *     classSignature         ::= [ typeparams ] supertype { interfacetype }
- *  </pre>
- *  <p>The type syntax in signatures is extended as follows:
- *  <pre>{@literal
- *     type       ::= ... | classtype | methodtype | typevar
- *     classtype  ::= classsig { '.' classsig }
- *     classig    ::= 'L' name [typeargs] ';'
- *     methodtype ::= [ typeparams ] '(' { type } ')' type
- *     typevar    ::= 'T' name ';'
- *     typeargs   ::= '<' type { type } '>'
- *     typeparams ::= '<' typeparam { typeparam } '>'
- *     typeparam  ::= name ':' type
- *  }</pre>
- *  <p>This class defines constants used in class files as well
- *  as routines to convert between internal ``.'' and external ``/''
- *  separators in class names.
- *
- *  <p><b>This is NOT part of any supported API.
- *  If you write code that depends on this, you do so at your own risk.
- *  This code and its internal interfaces are subject to change or
- *  deletion without notice.</b> */

- * Options for javac.
- * The specific Option to handle a command-line option can be found by calling
- * {@link #lookup}, which search some or all of the members of this enum in order,
- * looking for the first {@link #matches match}.
- * The action for an Option is performed {@link #handleOption}, which determines
- * whether an argument is needed and where to find it;
- * {@code handleOption} then calls {@link #process process} providing a suitable
- * {@link OptionHelper} to provide access the compiler state.

-         * {@linkplain Character#isWhitespace(int) white space}.
-         * The line count of the result will be the same as line count of this
-         * string.

-         * @implNote
-         * This method treats all {@linkplain Character#isWhitespace(int) white space}
-         * characters as having equal width. As long as the indentation on every
-         * line is consistently composed of the same character sequences, then the
-         * result will be as described above.

-/**
- * The FilerImplementation class must maintain a number of
- * constraints.  First, multiple attempts to open the same path within
- * the same invocation of the tool results in an IOException being
- * thrown.  For example, trying to open the same source file twice:
- *
- * <pre>
- * createSourceFile("foo.Bar")
- * ...
- * createSourceFile("foo.Bar")
- * </pre>
- *
- * is disallowed as is opening a text file that happens to have
- * the same name as a source file:
- *
- * <pre>
- * createSourceFile("foo.Bar")
- * ...
- * createTextFile(SOURCE_TREE, "foo", new File("Bar"), null)
- * </pre>
- *
- * <p>Additionally, creating a source file that corresponds to an
- * already created class file (or vice versa) also results in an
- * IOException since each type can only be created once.  However, if
- * the Filer is used to create a text file named *.java that happens
- * to correspond to an existing class file, a warning is *not*
- * generated.  Similarly, a warning is not generated for a binary file
- * named *.class and an existing source file.
- *
- * <p>The reason for this difference is that source files and class
- * files are registered with the tool and can get passed on as
- * declarations to the next round of processing.  Files that are just
- * named *.java and *.class are not processed in that manner; although
- * having extra source files and class files on the source path and
- * class path can alter the behavior of the tool and any final
- * compile.
- *
- * <p><b>This is NOT part of any supported API.
- * If you write code that depends on this, you do so at your own risk.
- * This code and its internal interfaces are subject to change or
- * deletion without notice.</b>

-# Messages in this file which use "placeholders" for values (e.g. {0}, {1})
-# are preceded by a stylized comment describing the type of the corresponding

-# The simple types currently in use are:
-#
-# annotation        annotation compound
-# boolean           true or false
-# diagnostic        a sub-message; see compiler.misc.*
-# fragment          similar to 'message segment', but with more specific type
-# modifier          a Java modifier; e.g. public, private, protected
-# file              a file URL
-# file object       a file URL - similar to 'file' but typically used for source/class files, hence more specific
-# flag              a Flags.Flag instance
-# name              a name, typically a Java identifier
-# number            an integer
-# option name       the name of a command line option
-# path              a path
-# profile           a profile name
-# source            a source version number, such as 1.5, 1.6, 1.7, taken from a com.sun.tools.javac.code.Source
-# source version    a source version number, such as 1.5, 1.6, 1.7, taken from a javax.lang.model.SourceVersion
-# string            a general string
-# symbol            the name of a declared type
-# symbol kind       the kind of a symbol (i.e. method, variable)
-# kind name         an informative description of the kind of a declaration; see compiler.misc.kindname.*
-# target            a target version number, such as 1.5, 1.6, 1.7, taken from a com.sun.tools.javac.jvm.Target
-# token             the name of a non-terminal in source code; see compiler.misc.token.*
-# tree tag          the name of a non-terminal in source code; see compiler.misc.token.*
-# type              a Java type; e.g. int, X, X<T>
-# url               a URL
-# object            a Java object (unspecified)
-# unused            the value is not used in this message
-#
-# The following compound types are also used:
-#
-# collection of X   a comma-separated collection of items; e.g. collection of type
-# list of X         a comma-separated list of items; e.g. list of type
-# set of X          a comma-separated set of items; e.g. set of modifier
-#
-# These may be composed:
-#
-# list of type or message segment
-#
-# The following type aliases are supported:
-#
-# message segment --> diagnostic or fragment
-# file name --> file, path or file object
-#
-# Custom comments are supported in parenthesis i.e.
-#
-# number (classfile major version)
-#
-# These comments are used internally in order to generate an enum-like class declaration containing
-# a method/field for each of the diagnostic keys listed here. Those methods/fields can then be used
-# by javac code to build diagnostics in a type-safe fashion.
-#
-# In addition, these comments are verified by the jtreg test test/tools/javac/diags/MessageInfo,
-# using info derived from the collected set of examples in test/tools/javac/diags/examples.
-# MessageInfo can also be run as a standalone utility providing more facilities
-# for manipulating this file. For more details, see MessageInfo.java.

-# boolean           true or false
-# diagnostic        a sub-message; see compiler.misc.*
-# fragment          similar to 'message segment', but with more specific type
-# modifier          a Java modifier; e.g. public, private, protected
-# file              a file URL
-# file object       a file URL - similar to 'file' but typically used for source/class files, hence more specific
-# flag              a Flags.Flag instance
-# name              a name, typically a Java identifier
-# number            an integer

-# path              a path
-# profile           a profile name
-# source            a source version number, such as 1.5, 1.6, 1.7, taken from a com.sun.tools.javac.code.Source

-# symbol            the name of a declared type
-# symbol kind       the kind of a symbol (i.e. method, variable)
-# kind name         an informative description of the kind of a declaration; see compiler.misc.kindname.*

-# type              a Java type; e.g. int, X, X<T>
-# url               a URL
-# object            a Java object (unspecified)
-# unused            the value is not used in this message
-#
-# The following compound types are also used:
-#
-# collection of X   a comma-separated collection of items; e.g. collection of type
-# list of X         a comma-separated list of items; e.g. list of type
-# set of X          a comma-separated set of items; e.g. set of modifier
-#
-# These may be composed:
-#
-# list of type or message segment
-#
-# The following type aliases are supported:
-#
-# message segment --> diagnostic or fragment
-# file name --> file, path or file object
-#
-# Custom comments are supported in parenthesis i.e.
-#
-# number (classfile major version)
-#
-# These comments are used internally in order to generate an enum-like class declaration containing
-# a method/field for each of the diagnostic keys listed here. Those methods/fields can then be used
-# by javac code to build diagnostics in a type-safe fashion.
-#
-# In addition, these comments are verified by the jtreg test test/tools/javac/diags/MessageInfo,
-# using info derived from the collected set of examples in test/tools/javac/diags/examples.
-# MessageInfo can also be run as a standalone utility providing more facilities
-# for manipulating this file. For more details, see MessageInfo.java.

-# Messages in this file which use "placeholders" for values (e.g. {0}, {1})
-# are preceded by a stylized comment describing the type of the corresponding

-# The simple types currently in use are:
-#
-# annotation        annotation compound
-# boolean           true or false
-# diagnostic        a sub-message; see compiler.misc.*
-# fragment          similar to 'message segment', but with more specific type
-# modifier          a Java modifier; e.g. public, private, protected
-# file              a file URL
-# file object       a file URL - similar to 'file' but typically used for source/class files, hence more specific
-# flag              a Flags.Flag instance
-# name              a name, typically a Java identifier
-# number            an integer
-# option name       the name of a command line option
-# path              a path
-# profile           a profile name
-# source            a source version number, such as 1.5, 1.6, 1.7, taken from a com.sun.tools.javac.code.Source
-# source version    a source version number, such as 1.5, 1.6, 1.7, taken from a javax.lang.model.SourceVersion
-# string            a general string
-# symbol            the name of a declared type
-# symbol kind       the kind of a symbol (i.e. method, variable)
-# kind name         an informative description of the kind of a declaration; see compiler.misc.kindname.*
-# target            a target version number, such as 1.5, 1.6, 1.7, taken from a com.sun.tools.javac.jvm.Target
-# token             the name of a non-terminal in source code; see compiler.misc.token.*
-# tree tag          the name of a non-terminal in source code; see compiler.misc.token.*
-# type              a Java type; e.g. int, X, X<T>
-# url               a URL
-# object            a Java object (unspecified)
-# unused            the value is not used in this message
-#
-# The following compound types are also used:
-#
-# collection of X   a comma-separated collection of items; e.g. collection of type
-# list of X         a comma-separated list of items; e.g. list of type
-# set of X          a comma-separated set of items; e.g. set of modifier
-#
-# These may be composed:
-#
-# list of type or message segment
-#
-# The following type aliases are supported:
-#
-# message segment --> diagnostic or fragment
-# file name --> file, path or file object
-#
-# Custom comments are supported in parenthesis i.e.
-#
-# number (classfile major version)
-#
-# These comments are used internally in order to generate an enum-like class declaration containing
-# a method/field for each of the diagnostic keys listed here. Those methods/fields can then be used
-# by javac code to build diagnostics in a type-safe fashion.
-#
-# In addition, these comments are verified by the jtreg test test/tools/javac/diags/MessageInfo,
-# using info derived from the collected set of examples in test/tools/javac/diags/examples.
-# MessageInfo can also be run as a standalone utility providing more facilities
-# for manipulating this file. For more details, see MessageInfo.java.

-# Messages in this file which use "placeholders" for values (e.g. {0}, {1})
-# are preceded by a stylized comment describing the type of the corresponding
-# values.
-# The simple types currently in use are:
-#
-# annotation        annotation compound
-# boolean           true or false
-# diagnostic        a sub-message; see compiler.misc.*
-# fragment          similar to 'message segment', but with more specific type
-# modifier          a Java modifier; e.g. public, private, protected
-# file              a file URL
-# file object       a file URL - similar to 'file' but typically used for source/class files, hence more specific
-# flag              a Flags.Flag instance
-# name              a name, typically a Java identifier
-# number            an integer
-# option name       the name of a command line option
-# source version    a source version number, such as 1.5, 1.6, 1.7
-# string            a general string
-# symbol            the name of a declared type
-# symbol kind       the kind of a symbol (i.e. method, variable)
-# kind name         an informative description of the kind of a declaration; see compiler.misc.kindname.*
-# token             the name of a non-terminal in source code; see compiler.misc.token.*
-# type              a Java type; e.g. int, X, X<T>
-# object            a Java object (unspecified)
-# unused            the value is not used in this message
-#
-# The following compound types are also used:
-#
-# collection of X   a comma-separated collection of items; e.g. collection of type
-# list of X         a comma-separated list of items; e.g. list of type
-# set of X          a comma-separated set of items; e.g. set of modifier
-#
-# These may be composed:
-#
-# list of type or message segment
-#
-# The following type aliases are supported:
-#
-# message segment --> diagnostic or fragment
-# file name --> file, path or file object
-#
-# Custom comments are supported in parenthesis i.e.
-#
-# number (classfile major version)
-#
-# These comments are used internally in order to generate an enum-like class declaration containing
-# a method/field for each of the diagnostic keys listed here. Those methods/fields can then be used
-# by javac code to build diagnostics in a type-safe fashion.
-#
-# In addition, these comments are verified by the jtreg test test/tools/javac/diags/MessageInfo,
-# using info derived from the collected set of examples in test/tools/javac/diags/examples.
-# MessageInfo can also be run as a standalone utility providing more facilities
-# for manipulating this file. For more details, see MessageInfo.java.

-/**
- * Root class for abstract syntax tree nodes. It provides definitions
- * for specific tree nodes as subclasses nested inside.
- *
- * <p>Each subclass is highly standardized.  It generally contains
- * only tree fields for the syntactic subcomponents of the node.  Some
- * classes that represent identifier uses or definitions also define a
- * Symbol field that denotes the represented identifier.  Classes for
- * non-local jumps also carry the jump target as a field.  The root
- * class Tree itself defines fields for the tree's type and position.
- * No other fields are kept in a tree node; instead parameters are
- * passed to methods accessing the node.
- *
- * <p>Except for the methods defined by com.sun.source, the only
- * method defined in subclasses is `visit' which applies a given
- * visitor to the tree. The actual tree processing is done by visitor
- * classes in other packages. The abstract class Visitor, as well as
- * an Factory interface for trees, are defined as inner classes in
- * Tree.

- * classes should, by convention, start with JC (javac).

-/**
- * Support for an abstract context, modelled loosely after ThreadLocal
- * but using a user-provided context instead of the current thread.
- *
- * <p>Within the compiler, a single Context is used for each
- * invocation of the compiler.  The context is then used to ensure a
- * single copy of each compiler phase exists per compiler invocation.
- *
- * <p>The context can be used to assist in extending the compiler by
- * extending its components.  To do that, the extended component must
- * be registered before the base component.  We break initialization
- * cycles by (1) registering a factory for the component rather than
- * the component itself, and (2) a convention for a pattern of usage
- * in which each base component registers itself by calling an
- * instance method that is overridden in extended components.  A base
- * phase supporting extension would look something like this:
- *
- * <pre>{@code
- * public class Phase {
- *     protected static final Context.Key<Phase> phaseKey =
- *         new Context.Key<Phase>();
- *
- *     public static Phase instance(Context context) {
- *         Phase instance = context.get(phaseKey);
- *         if (instance == null)
- *             // the phase has not been overridden
- *             instance = new Phase(context);
- *         return instance;
- *     }
- *
- *     protected Phase(Context context) {
- *         context.put(phaseKey, this);
- *         // other initialization follows...
- *     }
- * }
- * }</pre>
- *
- * <p>In the compiler, we simply use Phase.instance(context) to get
- * the reference to the phase.  But in extensions of the compiler, we
- * must register extensions of the phases to replace the base phase,
- * and this must be done before any reference to the phase is accessed
- * using Phase.instance().  An extended phase might be declared thus:
- *
- * <pre>{@code
- * public class NewPhase extends Phase {
- *     protected NewPhase(Context context) {
- *         super(context);
- *     }
- *     public static void preRegister(final Context context) {
- *         context.put(phaseKey, new Context.Factory<Phase>() {
- *             public Phase make() {
- *                 return new NewPhase(context);
- *             }
- *         });
- *     }
- * }
- * }</pre>
- *
- * <p>And is registered early in the extended compiler like this
- *
- * <pre>
- *     NewPhase.preRegister(context);
- * </pre>
- *
- *  <p><b>This is NOT part of any supported API.
- *  If you write code that depends on this, you do so at your own risk.
- *  This code and its internal interfaces are subject to change or
- *  deletion without notice.</b>

-/**
- * A rich diagnostic formatter is a formatter that provides better integration
- * with javac's type system. A diagnostic is first preprocessed in order to keep
- * track of each types/symbols in it; after this information is collected,
- * the diagnostic is rendered using a standard formatter, whose type/symbol printer
- * has been replaced by a more refined version provided by this rich formatter.
- * The rich formatter currently enables three different features: (i) simple class
- * names - that is class names are displayed used a non qualified name (thus
- * omitting package info) whenever possible - (ii) where clause list - a list of
- * additional subdiagnostics that provide specific info about type-variables,
- * captured types, intersection types that occur in the diagnostic that is to be
- * formatted and (iii) type-variable disambiguation - when the diagnostic refers
- * to two different type-variables with the same name, their representation is
- * disambiguated by appending an index to the type variable name.
- *
- * <p><b>This is NOT part of any supported API.
- * If you write code that depends on this, you do so at your own risk.
- * This code and its internal interfaces are subject to change or
- * deletion without notice.</b>

-/**
- * Utility class only for sjavac logging.
- *
- * Logging in sjavac has special requirements when running in server/client
- * mode. Most of the log messages is generated server-side, but the server
- * is typically spawned by the client in the background, so the user usually
- * does not see the server stdout/stderr. For this reason log messages needs
- * to relayed back to the client that performed the request that generated the
- * log message. To support this use case this class maintains a per-thread log
- * instance so that each connected client can have its own instance that
- * relays messages back to the requesting client.
- *
- * On the client-side (or when running sjavac without server-mode) there will
- * typically just be one Log instance.

- * takes as long as recompiling a single java file in that package,

- *
- * It is also educational to see package dependencies triggering recompilation of

- * the visible recompilation of the dependent packages indicates how much circular
- * dependencies your code has.

- * <h2 style="font-family:'DejaVu Sans Mono', monospace; font-style:italic">javac</h2>
- *
- * <p>
- * This module provides the equivalent of command-line access to <em>javac</em>
- * via the {@link java.util.spi.ToolProvider ToolProvider} and
- * {@link javax.tools.Tool} service provider interfaces (SPIs),
- * and more flexible access via the {@link javax.tools.JavaCompiler JavaCompiler}
- * SPI.</p>
- *
- * <p> Instances of the tools can be obtained by calling
- * {@link java.util.spi.ToolProvider#findFirst ToolProvider.findFirst}
- * or the {@linkplain java.util.ServiceLoader service loader} with the name
- * {@code "javac"}.
- *
- * <p>
- * In addition, instances of {@link javax.tools.JavaCompiler.CompilationTask}
- * obtained from {@linkplain javax.tools.JavaCompiler JavaCompiler} can be
- * downcast to {@link com.sun.source.util.JavacTask JavacTask} for access to
- * lower level aspects of <em>javac</em>, such as the
- * {@link com.sun.source.tree Abstract Syntax Tree} (AST).</p>
- *
- * <p>This module uses the {@link java.nio.file.spi.FileSystemProvider
- * FileSystemProvider} API to locate file system providers. In particular,
- * this means that a jar file system provider, such as that in the
- * {@code jdk.zipfs} module, must be available if the compiler is to be able
- * to read JAR files.

-/**
- * Deprecation Scanner tool. Loads API deprecation information from the
- * JDK image, or optionally, from a jar file or class hierarchy. Then scans
- * a class library for usages of those APIs.
- *
- * TODO:
- *  - audit error handling throughout, but mainly in scan package
- *  - handling of covariant overrides
- *  - handling of override of method found in multiple superinterfaces
- *  - convert type/method/field output to Java source like syntax, e.g.
- *      instead of java/lang/Character.isJavaLetter(C)Z
- *      print void java.lang.Character.isJavaLetter(char)boolean
- *  - more example output in man page
- *  - more rigorous GNU style option parsing; use joptsimple?
- *
- * FUTURES:
- *  - add module support: --add-modules, --module-path, module arg
- *  - load deprecation declarations from a designated class library instead
- *    of the JDK
- *  - load deprecation declarations from a module
- *  - scan a module (but a modular jar can be treated just a like an ordinary jar)
- *  - multi-version jar

-JDeprScan Internals
------
-
-**EXPERIMENTAL OPTIONS**
-
-    --Xload-class CLASSNAME
-
-        Loads deprecation data from the class named CLASSNAME instead of from
-        the JDK image.
-
-    --Xload-csv CVSFILE
-
-        Loads deprecation data from file CSVFILE.
-
-    --Xload-dir DIR
-
-        Loads deprecation data from the class hierarchy rooted
-        at the directory named DIR.
-
-    --Xload-jar JARFILE
-
-        Loads deprecation data from the classes contained in the
-        jar file named JARFILE.
-
-    --Xload-jdk9 JAVA_HOME
-
-        Loads deprecation data from a modular JDK whose home
-        directory is at JAVA_HOME. This essentially adds the given
-        path to the system-modules location.
-
-    --Xload-old-jdk JAVA_HOME
-
-        Loads deprecation data from an old (non-modular) JDK whose
-        home directory is at JAVA_HOME. This essentially scans the
-        rt.jar file from that JDK.
-
-    --Xload-self
-
-        Loads deprecation data from the running JDK image by
-        traversing the entire jrt: filesystem. This differs from
-        -release 9, which traverses modules, packages, and classes by
-        starting from a set of root modules and using javax.lang.model
-        mechanisms (as opposed to filesystem mechanisms) for
-        traversing contained elements recursively.
-
-    --Xcompiler-arg ARG
-
-        Adds ARG to the list of arguments passed to the compiler.
-
-    --Xcsv-comment COMMENT
-
-        Adds a comment line containing COMMENT to the top of the CSV
-        that is emitted.  Valid only when --Xprint-csv is
-        specified. More than one --Xcsv-comment option is permitted,
-        which will cause a corresponding number of comment lines to be
-        emitted to the CSV file.
-
-    --Xprint-csv
-
-        Prints out the loaded deprecation information in CSV format
-        to standard output. In this mode, no scanning is done, so
-        there must not be any additional directory, jar, or classname
-        arguments.
-
-**CSV FILE SYNTAX**
-
-The `-Xprint-csv` option causes **jdeprscan** to emit the loaded
-deprecation data in CSV (comma-separated value) format.  The general
-syntax of CSV is documented in [RFC 4180][RFC] with supplemental
-information in a [Wikipedia article][wiki].
-
-The file is encoded in UTF-8.
-
-The file consists of a series of lines. Any of the standard line
-separators CR (U+000D), LF (U+000A), or a CR immediately followed by
-LF, are supported. Newlines are only supported between records and
-are not supported within field values.
-
-Comment lines start with a `#` (U+0023) character in the first
-column. The entire line is ignored up until the next line separator
-sequence.
-
-Each line is divided into fields separated by the comma `,` (U+002C)
-character.  Horizontal whitespace is not treated specially; that is,
-it is considered part of a field's value. An empty line is considered
-to have one field which is the empty string.
-
-A field value that contains a comma or a quote quotation mark `"`
-(U+0022) must be surrounded by quotation marks. The surrounding
-quotation marks are not considered part of the field value. Any
-quotation marks that are part of a field value must be repeated in
-addition to being surrounded by quotation marks.
-
-It is a syntax error if a quotation mark appears within an unquoted field;
-if a quoted field isn't immediately followed by a comma or line
-separator; or if a quoted field is left unclosed at the end of the line.
-
-For example, a record with the following four fields:
-
-1. abcd
-2. ef,gh
-3. ij"kl
-4. mnop
-
-would be encoded as follows:
-
-        abcd,"ef,gh","ij""kl",mnop
-
-**CSV FILE DATA**
-
-The first line of output must be the following:
-
-        #jdepr1
-
-This is strictly a comment line, but it serves as a file
-identifier. The "1" indicates version 1 of this file.
-
-Zero or more comment lines follow, containing text that is specified
-by the `-Xcsv-comment` options.
-
-Subsequent non-comment lines must have the following five fields:
-
-        kind,typeName,descOrName,since,forRemoval
-
-Fields are defined as follows:
-
- * _kind_ - one of CONSTRUCTOR, FIELD, METHOD, ENUM\_CONSTANT,
-   CLASS, INTERFACE, ENUM, or ANNOTATION\_TYPE. These correspond to
-   enumeration constants from the `javax.lang.model.element.ElementKind`
-   enum.
-
- * _typeName_ - the fully qualified name of the type (if *kind* is
-   CLASS, INTERFACE, ENUM, or ANNOTATION\_TYPE) or of the enclosing
-   type (if _kind_ is CONSTRUCTOR, FIELD, METHOD, or
-   ENUM\_CONSTANT). This value is a _binary name_ [JLS 13.1][jls131]
-   using a slash character `/` (U+002F) to separate package and
-   top-level name components, and a dollar sign `$` (U+0024) to
-   separate nested name components. For example, the `Thread.State`
-   enum that appears in Java SE would have the following typeName:
-
-            java/lang/Thread$State
-
- * _descOrName_ - if _kind_ is METHOD or CONSTRUCTOR, this is the method's
-   or constructor's descriptor [JVMS 4.3.3][jvms433]; if _kind_ is FIELD or
-   ENUM\_CONSTANT, this is its name; otherwise this field is empty.
-   A method's descriptor includes its name, parameter types, and return
-   type. For example, the method
-
-           public void String.getBytes(int srcBegin,
-                                       int srcEnd,
-                                       byte[] dst,
-                                       int dstBegin)
-
-   has the descriptor
-
-           getBytes(II[BI)V
-
- * _since_ - the value of the `since` element of the `@Deprecated`
-   annotation, or empty if this element is not present.
-
- * _forRemoval_ - the value of the `forRemoval` element of the
-   `@Deprecated` annotation, a boolean, either "true" or "false".
-
-Note that the _since_ field can have arbitrary text (excluding
-line separators) and is thus subject to quoting.
-
-**EXAMPLE OUTPUT**
-
-Given the following method declaration and annotation from the
-`java.lang.Character` class,
-
-            @Deprecated(since="1.1")
-            public static boolean isJavaLetter(char ch)
-
-the following line will be emitted from **jdeprscan -Xprint-csv**:
-
-            METHOD,java/lang/Character,isJavaLetter(C)Z,1.1,false

-
-**DESCRIPTION**
-
-**jdeprscan** scans a class library for uses of deprecated APIs.
-**jdeprscan** processes one or more arguments, which can be any
-combination of a directory, a jar file, or a class name.
-
-A directory argument must specify a path to a directory hierarchy that
-reflects the Java package hierarchy of the classes it contains.
-**jdeprscan** will scan each class found in the directory hierarchy
-and report information about how those classes use deprecated APIs.
-
-Given a jar file, **jdeprscan** will scan the classes found within
-that jar file and report information about how those classes use
-deprecated APIs.
-
-Given a class file, **jdeprscan** will scan that class and report
-its use of deprecated APIs.
-
-Given a class name, **jdeprscan** will search for that class on the
-classpath, scan that class, and report information about how that
-class uses deprecated APIs. The class name must use the fully
-qualified binary name of the class, as described in the
-[Java Language Specification, section 13.1][jls131]. This form uses
-the '$' character instead of '.' as the separator for nested class names.
-For example, the `Thread.State` enum would be specified using the string
-
-        java.lang.Thread$State
-
-The `--class-path` option specifies the classpath used for
-class searching. The classpath is used for classes named on the
-command line, as well as for dependencies of the classes in jar file
-or directory hierarchy to be scanned.
-
-The `--for-removal` option limits output to uses of deprecated APIs
-whose `@Deprecated` annotation includes the `forRemoval` element with
-the value `true`. Note: the `forRemoval` attribute of the
-`@Deprecated` annotation did not exist prior to Java SE 9, so this
-option cannot be used with a release value of 6, 7, or 8.
-
-The `--release` option specifies the Java SE specification version
-that determines the set of deprecated APIs for which scanning is
-done. This is useful if a deprecation report is desired that lists
-uses of deprecated APIs as of a particular release in the past. If no
-`--release` option is given, the latest release is used.
-
-The `--list` and `-l` options will list the known set of deprecated
-APIs instead of doing any scanning. Since no scanning is done,
-no directory, jar, or class arguments should be provided. The set
-of deprecated APIs listed is affected by the `--release` and the
-`--for-removal` options.
-
-
-**EXAMPLE OUTPUT**
-
-The output is a report that lists program elements that use deprecated
-APIs. Output is subject to change.
-
-Consider the following declarations:
-
-        // java.lang.Boolean
-
-        @Deprecated(since="9")
-        public Boolean(boolean value)
-
-        // java.lang.Thread
-
-        @Deprecated(since="1.5", forRemoval=true)
-        public void destroy()
-
-Running **jdeprscan** over a class that calls these methods will result
-in output something like the following:
-
-        class Example uses method java/lang/Boolean.<init>(Z)V deprecated
-        class Example uses method java/lang/Thread.destroy()V deprecated for removal
-
-Running **jdeprscan** with the `--list` option will result in output
-including something like the following:
-
-        ...
-        @Deprecated(since="9") java.lang.Boolean(boolean)
-        @Deprecated(since="1.5", forRemoval=true) void java.lang.Thread.destroy()
-        ...
-
-**NOTES**
-
-The **jdeprscan** tool operates by opening Java class files and
-reading their structures directly, particularly the constant
-pool. Because of this, **jdeprscan** can tell _that_ a deprecated API
-is used, but it often cannot tell _where_ in the class that API is
-used.
-
-The **jdeprscan** tool doesn't follow the same set of rules for
-emitting warnings as specified for Java compilers in [JLS section
-9.6.4.6][jls9646]. In particular, **jdeprscan** does not respond to
-the `@SuppressWarnings` annotation, as that is significant only in
-source code, not in class files. In addition, **jdeprscan** emits
-warnings even if the usage is within the API element that is
-deprecated and when the use and declaration are within the same
-outermost class.

-package java.lang.annotation;
-
-/**
- * The constants of this enumerated type provide a simple classification of the
- * syntactic locations where annotations may appear in a Java program. These
- * constants are used in {@link java.lang.annotation.Target Target}
- * meta-annotations to specify where it is legal to write annotations of a
- * given type.
- *
- * <p>The syntactic locations where annotations may appear are split into
- * <em>declaration contexts</em> , where annotations apply to declarations, and
- * <em>type contexts</em> , where annotations apply to types used in
- * declarations and expressions.
- *
- * <p>The constants {@link #ANNOTATION_TYPE}, {@link #CONSTRUCTOR}, {@link
- * #FIELD}, {@link #LOCAL_VARIABLE}, {@link #METHOD}, {@link #PACKAGE}, {@link
- * #MODULE}, {@link #PARAMETER}, {@link #TYPE}, and {@link #TYPE_PARAMETER}
- * correspond to the declaration contexts in JLS 9.6.4.1.
- *
- * <p>For example, an annotation whose type is meta-annotated with
- * {@code @Target(ElementType.FIELD)} may only be written as a modifier for a
- * field declaration.
- *
- * <p>The constant {@link #TYPE_USE} corresponds to the type contexts in JLS
- * 4.11, as well as to two declaration contexts: type declarations (including
- * annotation type declarations) and type parameter declarations.
- *
- * <p>For example, an annotation whose type is meta-annotated with
- * {@code @Target(ElementType.TYPE_USE)} may be written on the type of a field
- * (or within the type of the field, if it is a nested, parameterized, or array
- * type), and may also appear as a modifier for, say, a class declaration.
- *
- * <p>The {@code TYPE_USE} constant includes type declarations and type
- * parameter declarations as a convenience for designers of type checkers which
- * give semantics to annotation types. For example, if the annotation type
- * {@code NonNull} is meta-annotated with
- * {@code @Target(ElementType.TYPE_USE)}, then {@code @NonNull}
- * {@code class C {...}} could be treated by a type checker as indicating that
- * all variables of class {@code C} are non-null, while still allowing
- * variables of other classes to be non-null or not non-null based on whether
- * {@code @NonNull} appears at the variable's declaration.
