Build Identifier: 

If entityManager is injected into a stateless scoped bean and further being injected by annotation into Application scoped beans, concurrent access may cause a collision in Hibernate session.

Reproducible: Sometimes

Steps to Reproduce:
1. write a test or use some tool that can post different resource to same iteration simultaneously
2. run it (i.e. 5 or more concurrent requests)
Actual Results:  
Found shared references to a collection org.hibernate.HibernateException
or connection has been closed exception or some other hibernate exception occures

Expected Results:  
Runs ok
