Hi Matteo, I just checked OpenJPA3 with JPA feature. The problem is about the javax.persistence version. Now, hibernate and eclipselink uses JPA 2.1 whereas OpenJPA uses JPA 2.2.
So, we can have a ClassCastException while trying to deal with both version in the same container. That's what happening by default on the provided example. I'm improving it. Anyway, I don't reproduce the issue. I guess that problem is that you don't use the correct JNDI name in persistence.xml.
