Udi -

You're really going to need to post more information than this for anyone to
figure out what is going on.... I understand you don't want to post your
application call stack, what about posting a filtered call stack? That might
be a good starting point.

You say you are enhancing your entities at runtime... is that via the
-javaagent or are you using the subclassing support?

Thanks,
