Description

A (java, sealed)
^
|
B (java, non-sealed)
^
|
C (groovy)

Error "cannot be non-sealed as it has no sealed parent" will occur while compiling the class C.

Java 19+ build fails because of the bug:

startup failed:
/home/daniel/IdeaProjects/groovy/src/test/org/codehaus/groovy/util/ReferenceManagerTest.groovy: 147: The class 'org.codehaus.groovy.util.ReferenceManagerTest$TestReference' cannot be non-sealed as it has no sealed parent.
 @ line 147, column 13.
       private class TestReference<T>
               ^
1 error
> Task :compileTestGroovy FAILED

Java 19+ declares java.lang.ref.Reference sealed.
