This is a bug that we found too late to change in Leopard GM.
/usr/bin/java, and the rest of the /usr/bin Java tools should work
in 64-bit on capable hardware.
Once again, our sincerest apologies,

I have a somewhat curious difference between the standard command-

This is on an erase-target-disk clean install of Leopard on a 2nd
generation Macbook Pro.

Okay, finally I got my Leopard DVD and installed it freshly on
Core 2

Then that can only mean you do not have 64-bit capable hardware. Do
$ sysctl hw.cpu64bit_capable
Do you see 1 as the output?
