Paul King commented on GROOVY-10290:
------------------------------------
Proposed PR:
https://github.com/apache/groovy/pull/1685
We actually write an instance method for non-static inner classes due to JVM
limitations for pre-16 JDKs:
https://github.com/apache/groovy/blob/master/src/main/java/org/codehaus/groovy/classgen/Verifier.java#L448-L451
But there is no need for that synthetic method to appear in the stubs.
> Dynamic Groovy code in Gradle doesn't compile because of $getLookup() method
> is not static
