Consider code like:
---
interface I {
     public String toString();
}
interface J extends I {}

I i = null;
i.toString(); //attributed as I.toString();
J j = null;
j.toString(); //attributed as j.toString();
---

This does not seem quite right - the method is inherited in "J" from "I", not from Object.

Moreover, calling `Elements.getAllMembers()` will return "toString" from "I" in the result, but calling `Trees.isAccessible(..., "toString", "I");` will return false, because it will appear that the method is implemented in j.l.Object.
