I don't know, but there is a Java language specification that you could go read :-)

What are you doing up so late/early? Aren't you on west coast time?

I get up earlier / go to bed earlier lately. (IT'S THIS MANHOOD THING, SO MUCH ENERGY...)

I'm pretty sure that overloading in a subclass and only changing the return type is forbidden. IMFO, IBazPrime won't compile.

Eclipse lets me get away with it. If I can't count on this behavior, I should probably change my code now ;)

Apparently Sun added covariant return types at some point:

Cool, thanks.

I think the answer to both questions is "yes", but I'm not sure. Have you yet answered the question for yourself? Let me know how it comes out, if you do.
