 * This test simulates EE container callbacks that could occur that affect em lifecycle state.

 * that is in the middle of a commit.
 * We only clear the entityManager if we are in the states
 * (Birth == 0, WriteChangesFailed==3, Death==5 or AfterExternalTransactionRolledBack==6).
 * If we are in one of the following *Pending states we defer the clear() to the release() call later
