-----------------------------
> Groovy calls wrong method if there is a static method on an interface
> ---------------------------------------------------------------------
>
> Key: GROOVY-7879
> URL: https://issues.apache.org/jira/browse/GROOVY-7879
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.4.7
> Reporter: Stefan Wolf
> Assignee: Paul King
> Fix For: 2.4.11
>
>
> If there is an interface having the static method {{foo}} and a class
> {{Impl}} implementing this interface also having a static method {{foo}},
> then calling {{Impl.foo()}} calls the method on the interface. For an easy
> self contained example have a look at
> https://github.com/wolfs/groovy-static-interface-method-test/blob/master/src/test/groovy/StaticInterfaceTest.groovy.
> This can yield class cast exceptions on Java 8 and from Java 9 build 125
> onwards this yields
> {code}
> java.lang.IncompatibleClassChangeError: Method ... must be InterfaceMethodref
> constant
> {code}
> This verification has been introduced here:
> https://bugs.openjdk.java.net/browse/JDK-8145148.
