> I have an application that starts four jgroups NotificationBus's that all share the same UDP transport (with          singleton_name="...") but are otherwise distinct.  Recently, the application started to fail to start with the following stack signature:

> I created a test application that does nothing but start these four busses, and if I start them simultaneously, I can always reproduce the above error.  I will attach the test application.
