I have a Xen f9 domU running under REHL5.2, I have installed JDK 1.5.0_15.
Now when ever i perfrom any Java command the systems give a Kernel OOPS
message and I have to reboot to make t work.

I've had various F8, F9 and centOS5.x domUs with Sun, GCJ and openJDK
JVMs under Xen on F8 and centOS5.x dom0s without any java problems.

Can you reproduce the issue without xen?

With java-1.6.0-openjdk-1.6.0.0-0.16.b09.fc9 I can run "java" (no arguments) just fine on my standalone machine (admitedly x86_64) but on an i386 pv I get the following on the console. I imagine that this is what the OP got.
