------------------------------------

             Summary: AsmDecompiler.parseClass fails against a Java 11 JEP 181 class
                 Key: GROOVY-8688
                 URL: https://issues.apache.org/jira/browse/GROOVY-8688
             Project: Groovy
          Issue Type: Bug
          Components: bytecode
    Affects Versions: 2.5.0
            Reporter: Robert Stupp


If {{AsmDecompiler.parseClass}} is invoked on Java 11 for a class that already uses [nest-based access control|http://openjdk.java.net/jeps/181], parsing with asm (on master) will fail with an {{UnsupportedOperationException}} in {{org.objectweb.asm.ClassVisitor#visitNestMemberExperimental}} or {{visitNestHostExperimental}}.

A trivial fix is to bump {{org.codehaus.groovy.control.CompilerConfiguration#ASM_API_VERSION}} to {{ASM7_EXPERIMENTAL}} with asm 6.2.

For the 2.5.x-branch, an upgrade from asm 6.1.1 to 6.2 is necessary.

 

[PR for GROOVY_2_5_x branch|https://github.com/apache/groovy/pull/768]

[PR for master branch|https://github.com/apache/groovy/pull/769]

{{./gradlew test}} is clean for both branches.

 

Side note: I've added the maven plugin to allow deployment of the artifacts into the local maven repo. I suspect, it should to removed from the PRs?
