Ed T commented on GROOVY-11805:
-------------------------------
the interesting part is that, if you didn't use GroovyShell and
GroovyClassLoader, and simply just wrote the code directly within the script,
the error doesn't happen. Something is also unique here with the use of
GroovyShell and GroovyClassLoader.
> Groovy5 compiler throws exception:
> "org.codehaus.groovy.ast.ClassNode.getGenericsTypes()" is null
