             Summary: IllegalStateException when the peristence bundle gets 
resolved.
                 Key: ARIES-933
                 URL: https://issues.apache.org/jira/browse/ARIES-933
             Project: Aries
          Issue Type: Bug
          Components: JPA
    Affects Versions: 0.3, 1.0
            Reporter: Ioannis Canellos


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.
