> When you close a Durable Subscriber right after it's being opened, in a race condition,  you could have one thread setting ReceiversReady(true) and another setting ReceiversReady(false).
> Change these test to run in repetition, and they will easily fail:
> PreserveOrderingTest::testPreserveOrderingTopicPersistent and testPreserveOrderingTopicNonPersistent will eventually fail
>    public void testPreserveOrderingTopicPersistent() throws Exception
>    {
>       for (int i=0;i<25;i++)
>       {
>          log.info("**************************************");
>          log.info("testPreserveOrderingTopicPersistent " + i);
>          log.info("**************************************");
>          preserveOrderingDurableSub(true);
