The EJBSpecUnitTestCase has a complex setup and the MDB run as related tests have been failing for a long long time. But debugging the issue has been pretty complex for a long long time now because the MDB tests fail arbitrarily. If the other tests are commented out, then the failing test that we are interested starts passing, thereby negating the effort of getting to the root cause. I am going to spend another 3-4 days on finding out why some of the MDB run as related tests are failing. If I am unable to solve them by then, then I am going to refactor the MDB run as tests into separate tests.
