I'm going to rant... right... NOW:
I really hope that RC1 was a joke... there are (in my mind) two HUGE blockers that should prevent any more builds from being called a release candidate:
Jikes compile support is totally broken. I've seen previous threads complaining this is a jikes bug and what-not... but the fact of the matter is that javac (make|rebuild|compile) all work, but jikes rarely does. This is an unacceptable regression! Anyone who has a large project can attest to the fact that jikes makes a huge difference in how long we wait around for a clean build. PLEASE PLEASE PLEASE get this fixed.
