Java HotSpot Virtual Machine

We have an application which calls a 3rd party supplied server API which has recently been upgraded to use Java 1.5

We are getting the following error reported by our client application. The application is also now running Java 1.5 but references many classes in jar files which would have quite old code in.

The supplier of the API has stated that the problem requires us to recompile all our jar files using v 1.5 ( including things like jconnect and jms ?!?!? ). This sounds like a bit of a cop-out to me, not to mention being impossible since we don't have the source for things like jconnect.

I suspect that there is a garbage collection problem at the bottom of all this, but I'm not sure how I can "prove" this, nor do I currently have any real clue as to how to fix any GC problem that may exist.

The application is supposed to wait for a message on a MQSeries queue and then transforms it via Xalan XSLT and sends it to a Server application. I've tried playing around with heap sizes etc but that just seems to make it worse. If I leave it at the settings that the previous version used then the client at least manages to process a couple of messages before core dumping. There doesn't seem to be a consistent trigger event to cause the core dump ( it's not a message arriving on a queue for example ) but it does seem to be fairly consistent timewise, i.e. after

Any ideas gratefully accepted.


Here's a logfile excerpt from my applications showing the Hotspot error message :
