------------------------------
> "PermittedSubclasses requires ASM9" when importing enum on Java 17
> ------------------------------------------------------------------
>
> Key: GROOVY-10194
> URL: https://issues.apache.org/jira/browse/GROOVY-10194
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 3.0.8
> Reporter: Peter Burka
> Assignee: Paul King
> Priority: Major
> Fix For: 3.0.9
>
>
> Java 17 (at least as of EA31) is now emitting "PermittedSubclasses"
> attributes for certain enum classes. When groovyc 3.0.8 encounters these, it
> crashes with an UnsupportedOperationException.
> h1. Test case:
> h2. {{AnEnum.java}}
> {code:java}
> public enum AnEnum
> {
> ONE() {
> @Override
> public String digit() {
> return "1";
> }
> };
> public abstract String digit();
> }
> {code}
> h2. {{Foo.groovy}}
> {code:groovy}
> import AnEnum
> {code}
> h2. Compile them...
> {code}
