-----------------------------------
I posted in the forum for this jira, but it looks like you did not follow up
that thread.
Hi Ioannis,
We have attempted this before. However, this will cause some other app server
to fail as they need EMF to perform entity enhancement using a mechanism other
than using ByteCodeWeaving.
See jira https://issues.apache.org/jira/browse/ARIES-832 for more details.
Thanks
Emily

> Aries JPA tries to create the entity manager factories when the persistence
> bundle gets in resolved state.
> With some persistence providers this can cause issues. For example Hibernate
> will try to access the datasource via jndi when creating the EMF, causing the
> IllegalStateException due to the fact that the persistnce bundle still has
> not context (is in resolved state).
> Even worse it will leave the EntityManagerFactoryManager is a wrong state,
> preventing it to create the EMF when the bundle is created.
> There are two ways of approaching this issue:
> i) Don't try to create EMF when the persistence bundle gets resolved.
> ii) Catch possible errors and cleanup, so that EMF can be created when the
> bundle gets started.
> I am going to attach a patch for the first appraoch, unless there is a good
> way for creating EMF when the bundle gets resolved.
