Eric Milles commented on GROOVY-11975:
--------------------------------------
Extension methods or meta-class methods are another consideration. Outside of
STC, the addition of an extension to the super class could change the call
target.
> STC: Groovy 5 can not compile super.foo with default interface method

> @CompileStatic
> interface IService {

> System.out.println(entity);
> }
> }
> @CompileStatic
> class TestGenericGroovy implements IService {
> void save(String entity) {
> // IService.super.save(entity) // works
> super.save(entity) // doesn't work: Groovyc: [Static type checking] -
> Default method save() requires qualified super
> }
> static void main(String[] args) {
> new TestGenericGroovy().save("test")
> }
> }
> {code}
> This seems to stem from issue GROOVY-10494.
> Now that Groovy supports interfaces natively without traits, it looks like
> this other fix is not necessary
