So, I guess that does lead me to a question :) How do we configure

to use a newer version of openjpa? I assume there is some option in

You should be able to use any OpenJPA 1.x version by simply deleting
the library we ship and dropping in your replacement. That's really
true of any JPA 1.0 implementation such as Hibernate or EclipseLink.
As Jacek mentions the JPA 2.0 thing hasn't been tried yet. If there
are no changes to the EntityManager interface, then it might work.
That'd be the biggest "if" to worry about. OpenEJB has an delegating
implementation of the EntityManager interface so it can support
TRANSACTION and EXTENDED PersistenceContexts. If there are new
methods in that interface, then it will break the container managed
persistence context code.
I'll pop on the OpenJPA dev list and see if I can't learn some more
info. Would be nice to find a way to allow people to experiment with
JPA 2.0 even if it means we have to be a little clever internally.
