Except of course that it should time out only new, unprepared tx created after the restart, not the prepared ones. Which come to think of it is true even in the non-restart case - you need to test that a prepared tx will not be timed out, or at least be concious of the issues that arise if it is. BTW, do you include inflight but unprepared tx in the list returned by a recover call on the XAResource? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186963#...
