If I compile* the following with javac and run, I get a NoSuchMethodError. Expect it to run without error.

public class DefaultClone {
  interface I1 {
    default Object clone() { return this; }
  }

  interface I2 extends I1 { }
  
  static class C implements I2 {
    public Object clone() { return this; }
  }

  static void test(I2 i) { i.clone(); }

  public static void main(String[] args) {
    test(new C());
  }
}

*Separately, the I1 declaration shouldn't compile at all -- see linked issue. So producing a future-proof test will require some non-Java bytecode generation.
