Java on Mac OSX: The Ball is in Oracle's Court
Sun (now Oracle) supplies Java for all other platforms. They have their own release schedules, which are almost always different than ours, so the Java we ship is always a version behind. This may not be the best way to do it.
It's clear that it's all down to Oracle from here, and the sooner they send a clear message to the community about their support, the better. On the plus side, Jobs makes a very good point that Java shouldn't need to lag behind. The cleanest way for Java on the Mac to work is to have it distributed just like the Windows versions.
