Issue during serialization inside a Entity Listener

> This involves serializing a copy of the object to put it on the JMS
> message.

> I ran into an issue where the serialization of the object causes a
> reentrant flush.  I was wondering if there is an easy way
> to make a copy of the object such that it can be serialized without
