Ja, Ja, Java 1.4

...

 

It takes more time to integrate into Mac OS X because the java threads are Mach threads. There's a lot more to making the best implementation, the best.

It shouldn't take more than a couple of months more to do it right.

 

The official reason for the hold up, and this comes from a developer conference from Apple, is they are completely reworking a lot of the code. Someone else would need to explain exactly how it works since I have no familiarity with Java but currently a lot of Apple's java implementation uses Carbon and they had hit limitations in what they wanted to do so everything that used carbon is now switching to cocoa.

This is why 1.4 is going to be amazingly late (they mentioned a month or two in the conference). However there are quite a few benefits once the switch is complete.
