I am looking for a sponsor and reviewers. The webrev is available at http://cr.openjdk.java.net/~jbachorik/JDK-7146162/webrev.03
As explained in the issue the failure is caused by the RMI connection heart-beat thread racing against the thread executing the MBean operation and encountering the IOException. The heart beat thread sets the the admin state to "terminated" but does not send the failure notifications. On the other side the operation thread determines the state to be already terminated and skips the notifications as well. The fix adds the call to handle an ioexception, including sending the failure notifications, to the hear-beat connection failure handler. Also it widens the synchronized block since the whole code block checking for the connection failure and recovering must be run atomically, Thanks, -JB-
