Shutdown of JTS

Kabir Khan Master

For AS 7 we are using jbossjts 4.11.0.Final, and I am seeing some problems on shutdown of a server instance. This does not happen every time but often enough on my machine. For about 65 seconds I see stack traces like:

Thread-3 is run by an executor as part of the server shutdown process, and from looking at the code it is waiting for Thread-6 to finish. Thread-6 is stuck in a Socket.connect(), so it sounds like whatever it is trying to connect to is open but no longer accepting connections. Can someone point me towards what TransactionStatusConnector is trying to connect to?
