Groovy parsing failure for `@Canonical` annotation on a class definition

[greg-at-moderne]

What version of OpenRewrite are you using?

Current main = e1f2efd

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

    @Test
    void canonical() {
        rewriteRun(
          groovy(
            """
              import groovy.transform.Canonical
              
              @Canonical
              class Person {
                  String name
                  int age
              }
              """
          )
        );
    }

added to rewrite-groovy/src/test/java/org/openrewrite/groovy/tree/AnnotationTest.java

fails with:

Caused by: java.lang.IllegalStateException: Unexpected class type:
