ManagedConnectionMBeanTest.testChannels fails on 0-10 spawned profiles

Keith Wall commented on QPID-3756:
----------------------------------
Problem is that there is a race condition between the broker, closing the connection and unregistering the connection mbean and the test using the mbean to observe the number of connections. When the test fails, the test makes the observation too soon.
On the 0-10 path, the broker unregisters the mbean (ServerConnection#closed) only after the socket has been closed (IoReceiver.java:175). This is after the broker has sent the ConnectionCloseOk to the client, so the clients #close() call will have already returned control to the caller.
On 0-8..0-9-1 the unregister is done much earlier (AMQProtocolEngine#closeSession) which is invoked on receipt of ConnectionClose, i.e. before the ConnectionCloseOkBody is sent so the same problem cannot occur.
We could change 0-10 to unregister the mbean from ServerConnectionDelegate.connectionClose() i.e. before the ConnectionCloseOk is sent to the client. Opinions anyone?

Keith Wall commented on QPID-3756:
----------------------------------
I've attached a patch to ConnectionDelegate.java to resolve this problem.
It works by reordering the ConnectionCloseOk response so that it occurs after the internal state is updated. Obviously this change will affect both client and broker. I did consider making the change Broker side only by overriding the method within ServerConnectionDelegate.java, but this would only serve to introduce more complexity and difference between broker/client. Robbie/Alex, what do you both think?

Robbie Gemmell updated QPID-3756:
---------------------------------
Status: Open (was: Ready To Review)
I dont see this as a test problem, this is a broker side issue.
As per Keith's original comment, I think we should be unregistering the MBean before responding to the client that the connection is closed, as occurs for 0-9-1 clients. Unregistering the MBean is part of the process of closing, and we should look to prevent the MBean being present and usable for any length of time after the connection is no longer considered live.

Robbie Gemmell commented on QPID-3756:
--------------------------------------
I think I might actually lean toward confining the change in behaviour to the broker. I recall doing that exact change when Alex and I were looking at the failover stuff last year, and we ended up reverting it. I cant remember what the precise reason but I think the change had unexpected failover related side effects on the client. The method already is overriden in ServerConnectionDelegate, albeit currently it subsequently calls the superclass implementation.
