Virtual Machine
FreeBSD Java is based on Intel, so it might be possible to apply it to port Mustang for Darwin, the underlying OS layer of Mac OS X on Intel Macs. One more feasible idea about the porting is making a headless version of Mustang for Intel Macs, i.e. core Java without graphic facilities such as AWT, Swing, and Java 2D.
Or, we can just wait for Leopard (Mac OS X 10.5) to come up with Mustang :-)
I completely switched my development platform to PowerPC G5 and got curious of whether Java on Mac OS X supports 64-bit mode. The answer is, there's no explicit option for the mode, but certainly some benefit explained at http://developers.sun.com/learning/javaoneonline/2004/javatechdesktop/TS... . Please correct me if I'm wrong about it and honestly, I wish some day we can see the option on Mac.
