Notes/Domino 6 and 7 Forum : JVM Memory - and tearing last of hair out !!

We have an application that uses 4 Java Agents, we are evaluating R6.5 and are running into JVM memory issues.

These agents run fine with NO recycling of objects or garbage collection on and R5 server, they are used extensively and never fall over.

On R6.5 they will only run about 20 times before the JVM runs out of memory and cannot get the attachments (.jar files) stored in the ScriptLibrary.

I have put in recycling and garbage collection into the agents but this still happens (they run a bit longer). I am not a Java expert, but cannot see why they run under R5 and Notr R6.5 I feel 6.5 has a memory leak problem...

My code is below any help pointers very much appreciated, as this may stop our entire Notes 6.5 rollout in its tracks...
