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

             Summary: Calling indirect default interface methods fails both dynamic/static compiled
                 Key: GROOVY-8693
                 URL: https://issues.apache.org/jira/browse/GROOVY-8693
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 2.5.0
            Reporter: Christoph Frick


Given _<interface> Intr <|- Impl <| SubImpl_ where _Intr_ is an Java8 interface with a default implementation, running _SubImpl_ fails both with _CompileDynamic:_

Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: sut.SubImpl.doSomething() is applicable for argument types: () values: []
Possible solutions: doSomething(), toString(), toString()
