Description

If the case mentioned in https://docs.groovy-lang.org/latest/html/documentation/#_default_conflict_resolution used static methods instead of instance methods, "T.super.m()" disambiguation is not available.

Consider the following:

trait A {
  static m() { 'A' }
}
trait B {
  static m() { 'B' }
}
class C implements A, B {
  void test() {
    print m() // prints "B"
    print A.super.m() // java.lang.IllegalArgumentException or some other compiler problem
    print B.super.m() // java.lang.IllegalArgumentException or some other compiler problem
  }
}
new C().test()​
