Error Deploying JPA Application in EAP 6 with Extended Persistence Context.

Issue

I’m having an issue with deploying a Java EE RESTful service to EAP that has a JPA library as one of its dependencies. The EntityManager injected into the JPA library's service class thusly:

@Stateless
@EJB(name = "DataService", beanName = "DataService", beanInterface = DataService.class)
@LocalBean
public class DataService implements GenericService
{
    @PersistenceContext(unitName = "convergence")
    private EntityManager em;

    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
    public <T> T create(T t)
...

Because we had to set the TransactionAttributeType.REQUIRES_NEW attribute on the create and update methods, our entities are detached and I can’t call the refresh method. So, I updated our PersistenceContext annotation be extended:

@Stateless
@EJB(name = "DataService", beanName = "DataService", beanInterface = DataService.class)
@LocalBean
public class DataService implements GenericService
{
    @PersistenceContext(unitName = "convergence", type=PersistenceContextType.EXTENDED)
    private EntityManager em;

. . . snip . . .
}

But, when I try to deploy the app, I get this error in JBoss EAP:

2014 Aug 13 13:51:23,560 Processor [http-/0.0.0.0:8080-3] ERROR ca.test.processor.resource.ProcessorResource - : Caught exception: JBAS011048: Failed to construct component instance
javax.ejb.EJBTransactionRolledbackException: JBAS011048: Failed to construct component instance

What does this error mean and how do I troubleshoot/fix it?
