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?
