Really?  With a 32-bit JVM?  I've never been able to get it to start
with any more than the ~1530MB limit and I found docs on Sun's site to
back that up -- different OS's place different limits under 2048MB for
various overheads.  I'd say you should count yourself very, very lucky
that the 2048MB's never ran into OOM conditions.  Still, odd that the
JVM won't even *start* under Xen...
