Thanks Rick,
I did as you said and yes it confirms that for some reason the enhancer is
not available. My preferred option was to not have to use the enhancer at
all and looking at the docs 5.2.2 I expected that if I deployed on Tomcat
1.6 and put in the OpenEJB plug-in, then the classes would be enhanced at
deployment time. Up until now I have been using the subclassing enhancer but
it seems to run every time create a new entity manager or persist entities,
the problem with that apart from performance is that I constantly face OOM
or stack overflow issues.
Am I wrong or shouldn't Tomcat 1.6 with the OpenEJB plug-in enabled, negate
the need for any runtime enhancement?

Chris -
Yes it looks like the -javaagent did not work. As a starting point to debug
this problem, I'd suggest setting
openjpa.RuntimeUnenhancedClasses=unsupported in your persistence.xml file to
disable the subclassing enhancement.
Let us know what you come up with.

When my application runs I receive warnings like below, which if I am
reading it correctly is telling me that the java agent is not working.
