Oracle proposes a change for the sake of uniqueness, but uniqueness is not copyrightable. And if non-copyrightable change is all you can reasonably do, then there's little if any room for creativity. Also it's obvious `max` is not a creative, but a traditional name for such function, not to mention one can't copyright a common word in wide use. There's no technical way to not copy the interface, especially method names, and imagine what happens when you implement an interface: it's copied verbatim.
