----------------------------------------

With approach (i) there are test failures, so I'll try the approach (ii).

> 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.
