Hi,
executing the JPA LRG tests on MySQL, I am observing the following issue with EntityManagerJUnitTestSuite.testLockWithJoinedInheritanceStrategy:
Exception Description: DriverWrapper: failed to instantiate null Internal Exception: java.lang.NullPointerException
Local Exception Stack:

So far, I have not been able to hunt it down.
Is anyone observing this also or knows how to fix this?
