> Since QPID-5710, there has been a possibility that the housekeeper can attempt to check that message status on queues that are not yet open, and this leads to an NPE as such queues have a null entry list.
> TransactionTimeoutTest occasionally shows this problem (see log excerpt below).  It does not cause a test failure as the housekeeper merely logs all exceptions and continues.
> It seems QPID-5710 introduced this possibility as it moved the creation of the queue entry list from construction time to onOpen().
