That's absolutely ridiculous. With this logic, any time I implement an interface that I didn't myself make, it's a copyright violation. I shouldn't even consider making something iterable because then Oracle could take me to court for violating their copyright. All I'm doing is implementing an API they laid out. In this case, it's clearly intended to be copied, but they can't have it both ways. It's either ok, or it isn't.
