What's new in Leopard from Java developer's PoV

Apple is going to release another cat - Leopard, aka Mac OS X 10.5 - to the wild tomorrow. Are there any news for Java developers?

According to some sources we will see good old Java 1.4.2 and 1.5.0 with latter as default. There is no sign of the latest Java 6 while almost a year passed since its release for other platforms.

It would be interesting to know what happened to "The ultimate platform for developing and deploying cross-platform Java applications" promise?

PS: Was it the reason James Gosling gave up on Mac OS X in favor of Solaris?
