Why put both client and server VMs on your LD_LIBRARY_PATH ?
Pick one of client or server and put that one only on your LD_LIBRARY_PATH.

Could it be that sudoing changes the environment you're in for some reason, 
causing LD_LIBRARY_PATH to no longer be correct ? (unsure myself).

Could it be that you installed Sun's java on your Debian box but didn't 'sudo 
update-java-alternatives' (an Ubuntu thing, maybe this doesn't exist on 
Debian) and you're picking up the 'wrong' default java (usually gcj-based).
(again unsure myself).

I've used Sun Java 1.5 and 1.6, and OpenJDK 1.7 (built myself) without any 
problem (on various Ubuntu installs and Win2k). On Mac OS X, I just use the 
installed Apple Java.
