Some tests assume that jdoPostLoad() will be called, but do not take into account the possibilty that persistent-nontransactional is a valid state, and that jdoPostLoad() is not invoked for those instances. The solution should be to force instances to be transitioned to persistent-clean after commit by setting RetainValues=false.
This affects the following tests:
The solution is to invoke "setRetainValues(false)" after obtaining the transaction in both the test cases. E.g.:
Transaction t = pm.currentTransaction();
