Java HotSpot Virtual Machine

I'm getting the standard "EXCEPTION_ACCESS_VIOLATION" error (message below), but with a twist.
This is a typical client/server environment with a CORBA ORB (ObjectBus). The twist is that this exception occurs only when there is a Java client or Java server being used with the ORB. If I use a C++ client and C++ server, there is no exception or any error.
Would a memory leak/free memory read in the C++ ORB STILL be responsible for this? (remember, the ORB does not barf if I use a C++ client and server).
(Btw, The ORB also has a JNI layer that communicates with Java clients and servers)
Any ideas?
Thanks in advance,
Kunal
