Description

Combination of GROOVY-9909 and GROOVY-10381. Consider the following:

package p;
public interface A {
  default void m() {
    System.out.print("A");
  }
}
public interface B {
  default void m() {
    System.out.print("B");
  }
}

class C implements p.A, p.B {
  void m() {
    A.super.m() // The variable [A] is undeclared
  }
  void test() {
    m()
  }
}

It is required to override m() to disambiguate the interface default methods. However, it is not possible to disambiguate the "super" reference with a type qualifier.
