Maybe something related to your persistence provider.

The error seems to be here:

>>>EntityManagerFactoryBuilder emfBuilder = phaseOnePersistenceUnitService.getEntityManagerFa    ctoryBuilder();

I'm not sure about the following, is just a hint...

Could you try add this line? <provider>org.hibernate.ejb.HibernatePersistence</provider>

Is the hibernate-entitymanager-<VERSION>.jar on your pom.xml?

Are you using jboss-deployment-structures.xml file? Could you provide it?
