hmm, very interesting.  What other processes are running outside the VM?
 
do you have process monitors, intrusion detection or other memory/IO intensive 
processes running on the same box?
 
you can rule out native drivers as a possible cause.
the VM still could be causing it.
tomcat is most likely not the cause.
 
that still leaves a lot of variables you have to track down. what are the exact system 
specs again?

I am not using any native drivers.

Not exactly, the segfault occurs in a routine outside the VM but it is hard to 
know what causes the memory corruption.
