Cranky much?

Maybe your board doesn't have a jazelle-capable part, or you lack licensing for it (jazelle isn't publicly documented, sadly). Maybe you do have a bunch of gates left over on your FPGA.

I mean, it looks like a cool hack to me.

Jazelle

http://en.wikipedia.org/wiki/Jazelle

The Jazelle extension requires paying money to access on how to set it up. Also as others have pointed out using hardware supported java prohibits a lot of dynamic optimizations.

ARM seem to be mostly concentrating on the ThumbEE environment now, which is much better documented.
