FinalizeLocalVariables might fail with IllegalStateException on a Kotlin or Groovy build script

[greg-at-moderne]

What version of OpenRewrite are you using?

OR current main (7edbbf01ab8a9b666ef3c2003ee7b8e0c66a4967)
rewrite-static-analysis (428d8b0)

What is the smallest, simplest way to reproduce the problem?

Add the following test to a new file src/test/java/org/openrewrite/staticanalysis/kotlin/FinalizeLocalVariablesTest.java:

    @Override
    public void defaults(RecipeSpec spec) {
        spec.recipe(new FinalizeLocalVariables());
    }

    @Test
    void kotlinVar() {
        rewriteRun(
          kotlin(
            """
            var x = 1
            """
          )
        );
    }
