java - org.apache.openjpa.persistence.PersistenceException: null

Question

The second line is causing the exception listed below. This code actually works on the test server, but is blowing up on my box. Can anyone offer a clue what I need to look at to solve this?

   TypedQuery<ed> _TypedQuery = _EntityManager.createQuery(_CriteriaQuery);
   List<ed>       _edList     = _TypedQuery.getResultList();

Exception

I'll document all my solutions to this problem.

• This is the 1st resolution. The clue was here. I upgraded Open JPA from 2.2.0 to 2.2.2 & the exception went away, so it appears that it was a bug.

• This happened again. I was missing cglib.2.2.3.zip and/or cglib-nodep-2.2.3.jar.
