The Cocoa/Java bridge has been deprecated for ages; other than that, I can't think of any other secret sauce that Apple spreads on their JVM (of course, if there were hidden APIs, and if the Apple JVM used them, and if Apple wanted them to stay secret, I wouldn't be able to say). Regardless, it's not like Java on OS X is going to disappear; if nothing else, Apple's internal usage of Java and their desire to eat their own dog food guarantees as much. This warning comes with considerably more heads-up than most such developer related warnings from Apple, so by the time 10.7 ships, I would imagine that an open JDK/JRE will be readily available.
