You don't need 64 bits to exceed 2GB in java. You need 64 bits to
exceed 4GB. On my brand new Core2Duo MBP with 3GB physical memory,
I'm getting:
$ java -Xmx2108M -version
java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-113)
Java HotSpot(TM) Client VM (build 1.5.0_06-68, mixed mode)
$ java -Xmx2109M -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Trace/BPT trap
That's bigger than 2GB, but just barely.

I've been trying to find out the details on using Java in 64 bit
mode in Mac OS/X. Is this possible under Java 5? If not is it
going to be possible in Java 6? I suppose what I'm really trying
to find out is if it is possible to heap sizes > 2GB.
Thx
