The other issue is related to the start/stop of the server.
We had problems starting EAP511 with the JBossTools4 defaults, so we changed (both) state detectors to JMX.
The server would start fine, but a stop always causes this:
Exception in thread "main" javax.naming.CommunicationException: Could not obtain connection to any of these urls: 0.0.0.0:1099 [Root exception is javax.naming.CommunicationException: Failed to connect to server /0.0.0.0:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server /0.0.0.0:1099 [Root exception is java.net.ConnectException: Connection refused: connect]!

And looking in one of the logs, we saw the below (note third entry):

So this happened as part of a server restart.
It may not be a full explanation, since some of the other developers don't restart unless they already see deployment problems....
I've asked them all to switch Shutdown Poller to 'Process Terminated' which I suspect will fix the problem when caused as a side effect of a bad shutdown.
