> I'm trying to extend from an abstract class and override one of its abstract methods. Another "final" concrete method of the same name exists in the abstract class.
> When I compile, it complains that i cannot override the method marked as final, however i've only overriden the abstract method, and not the "final" one.
> This issue is sporadic. The error pops up and goes after several retries
> I've attached a simple project that reproduces this issue. The error may or may not happen the first time. Tweaking the code here and there, gets the issue to pop up
> Here's a sample of the error message
> bq. Error:Groovyc: You are not allowed to override the final method copy(org.apache.calcite.plan.RelTraitSet -> org.apache.calcite.plan.RelTraitSet,java.util.List -> java.util.List <E extends java.lang.Object>) from class 'org.apache.calcite.rel.core.Join'.
