Monitoring DB2 JVM

The way I understand it, stored procedures which are written in Java
will execute in a JVM on the DB2 server. We've had a memory leak with
one or more of our stored procs for a while. I would like to do
systematic approach to determine which one(s) may be leaking. Is there
a way to watch/monitor the memory in the JVM used by DB2 when invoking
a stored procedure?
