I would expect 64-bit Java to use 64-bit object pointers, and 32-bit Java to use 32-bit object
pointers.  Given how often object pointers occur in typical Java programs, that's a fair bit
of extra memory.  If you assume that half of a typical object's state is references to other
objects, then (naively) you'll use 50% more memory.

Now I'll sit back and wait for Chuck to contradict me :-).
