Running org.apache.qpid.test.unit.xa.FaultTest.testPrepare() seems to
cause the C++ broker to send SessionKnownCompletedBody after
SessionDetachBody in some cases.
I think this is an unintended consequence of
http://svn.apache.org/viewvc?view=revision&revision=828108, specifically
http://svn.apache.org/viewvc/qpid/trunk/qpid/cpp/src/qpid/amqp_0_10/SessionHandler.cpp?r1=828108&r2=828107&pathrev=828108
The sending of known-completed is triggered by receiving a
session-completed from the client. All session controls are now always
invoked where previously they were ignored (apart from session-detached)
after a detach was issued.
When the broker sends SessionDetachBody to the java client it removes
the session from it's map.
(Line 361 in Connection.java)
The broker then sends SessionKnownCompletedBody which results in a
NullPointer on the java client side as it tries to dispatch this
method on the session it has just removed.
(Line 318 in Connection.java)
This test seems to pass in some servers, all though it fails for me.
This could be due to a race condition on the broker side inside DtxManager.cpp.
I haven't had time to debug this yet, will do so tomorrow unless
somebody gets to it first.
