This rule raises an issue when a class implements the cache key generator interface but does not provide a mechanism for the caching framework to +instantiate it, either through a default constructor or through registration with the dependency injection container.

+

In Java, this specifically refers to the CacheKeyGenerator interface and CDI (Contexts and Dependency Injection) bean annotations.

+

Why is this an issue?

+

When implementing a custom cache key generator interface in the framework, the caching subsystem must be able to create instances of your +implementation class. The framework supports two instantiation mechanisms:

+
    +
  • Managed component injection: If your class is registered as a managed component in the dependency injection container + (annotated with scope management annotations that mark it as application-scoped, request-scoped, dependent-scoped, etc.), the framework will use the + container to create and manage instances.
  • +
  • Public no-args constructor: If your class is not a managed component, the framework will create new instances using reflection + by calling a public no-args constructor.
  • +
+

When a cache key generator implementation lacks both of these, the framework cannot instantiate it. This prevents the cache from generating keys +properly.

+

The problem typically manifests when developers try to pass configuration or dependencies through constructor parameters without providing an +alternative instantiation path. While the intention may be to configure the key generator, this approach breaks the framework’s ability to create +instances.

+

What happens at runtime

+

When the cache attempts to use your key generator, the framework will try to instantiate it. Without a valid instantiation mechanism:

+
    +
  • The framework cannot create an instance of your generator
  • +
  • A runtime exception will be thrown when cache operations occur
  • +
  • Cache annotations that reference your generator will fail
  • +
+

This failure occurs during actual cache operations, not at application startup, making it harder to detect during development.

+

What is the potential impact?

+

When custom cache key generator implementations cannot be instantiated, the application will fail at runtime when cache operations attempt to use +the key generator. This breaks caching functionality for any methods that reference the problematic generator.

+

Users will experience:

+
    +
  • Failed cache lookups and invalidations
  • +
  • Broken cache-related functionality, potentially affecting application performance if caching is critical
  • +
  • Possible application crashes if exceptions are not properly handled
  • +
  • Degraded performance if the caching layer becomes unavailable
  • +
  • Errors that only appear during actual usage, making them harder to detect during development
  • +
+

Since the failure happens at runtime rather than build time, it may not be caught during development and could reach production environments.

+

How to fix it in Quarkus

+

Convert your CacheKeyGenerator implementation into a CDI bean by adding a scope annotation like @ApplicationScoped or +@Dependent. This allows you to inject dependencies normally while letting Quarkus manage the instance lifecycle.

+

Code examples

+

Noncompliant code example

+
+public class CustomKeyGen implements CacheKeyGenerator {
+    private final ConfigService configService;
+
+    public CustomKeyGen(ConfigService configService) { // Noncompliant
+        this.configService = configService;
+    }
+
+    @Override
+    public Object generate(Method method, Object... methodParams) {
+        String prefix = configService.getPrefix();
+        return new CompositeCacheKey(prefix, methodParams[0]);
+    }
+}
+
+

Compliant solution

+
+@ApplicationScoped
+public class CustomKeyGen implements CacheKeyGenerator {
+    @Inject
+    ConfigService configService;
+
+    @Override
+    public Object generate(Method method, Object... methodParams) {
+        String prefix = configService.getPrefix();
+        return new CompositeCacheKey(prefix, methodParams[0]);
+    }
+}

⚠️ Quality: Redundant quarkus-cache dependency conflicts with local mock interface 📄 java-checks-test-sources/default/pom.xml:189-194 📄 java-checks-test-sources/default/src/main/java/io/quarkus/cache/CacheKeyGenerator.java:8-9 The PR adds the real `io.quarkus:quarkus-cache:3.2.0.Final` dependency in pom.xml AND also adds a hand-written mock `io/quarkus/cache/CacheKeyGenerator.java` with the same fully-qualified name. The PR description states the mock was created "avoiding external dependency", which directly contradicts also adding the dependency. Having both a local source file and a jar that define `io.quarkus.cache.CacheKeyGenerator` on the same compile path is at best redundant and can cause type-resolution ambiguity / duplicate-type issues in the test-sources module. Pick one approach: either rely on the real dependency and delete the mock, or keep the mock and drop the new dependency from pom.xml (consistent with the stated intent). Note the real Quarkus `CacheKeyGenerator` also declares a default `boolean generationGroup()` method, so the mock is not a faithful copy.
💡 Edge Case: Implicit constructor of package-private class treated as public 📄 java-checks/src/main/java/org/sonar/java/checks/quarkus/CacheKeyGeneratorInstantiableCheck.java:86-98 📄 java-checks/src/main/java/org/sonar/java/checks/quarkus/CacheKeyGeneratorInstantiableCheck.java:49-51 `hasPublicNoArgsConstructor` returns true when the no-arg constructor's `declaration() == null` (implicit default constructor), regardless of visibility. An implicit default constructor inherits the class's access level, so for a package-private (or private nested) class implementing `CacheKeyGenerator` the implicit constructor is NOT public. The issue message explicitly tells users to add a "public no-args constructor", yet such a class is reported compliant — an inconsistency that can produce a false negative if Quarkus requires a public constructor for non-CDI instantiation. Consider also checking the effective visibility of the implicit constructor (e.g. require the class itself to be public), or align the message with the actual check. Also note records/enums implementing the interface are not covered since `nodesToVisit()` only registers `Tree.Kind.CLASS`.

Quality: Missing S8909 rule metadata (HTML + JSON) breaks build > 📄 java-checks/src/main/java/org/sonar/java/checks/quarkus/CacheKeyGeneratorInstantiableCheck.java:30 > The new rule `CacheKeyGeneratorInstantiableCheck` is annotated with `@Rule(key = "S8909")` and is auto-registered via `CheckListGenerator`, but no metadata files exist for it. `GeneratedCheckListTest` asserts that both `org/sonar/l10n/java/rules/java/S8909.html` and `S8909.json` exist for every registered rule (see GeneratedCheckListTest.java:137-142), and a Glob confirms neither file is present. Without these the rule has no description, no severity/type/profile assignment, and the test suite (hence the build) will fail. Add `S8909.html` (rule description) and `S8909.json` (metadata: title, type, status, tags, remediation, default severity, and SonarWay profile membership) under `java-checks/src/main/resources/org/sonar/l10n/java/rules/java/`.
