As I said, I don't think there's a rule that requires @Override. Thanks for
verifying this. :-)
I'm not proposing adding such a rule either. I agree, it adds little benefit, at
least for the JDK, and it adds clutter.
A quick grep reveals over 33,000 occurrences of @Override in the JDK sources.
That seems like a lot, but if we were to add it to all locations where it could
be applied, this might add hundreds if not thousands more occurrences. I'm not
sure it's worth the effort to do either the additions or the removals that'd be
necessary to make things consistent. Oh well.
