Matt Hogstrom commented on GERONIMO-3520:
-----------------------------------------
Viet, for the txmanager patch I think there may be an issue with the use of the
static long. Since the access is not synchronized there exists a strong
possibility of lost updates in a heavily concurrent system which would lead to
inaccurate values. volatile is one way to address this problem but I don't
think it is perfect on all VMs so I think the better solution would be the use
of java.util.concurrent.atomic.AtomicLong .getAndIncrement() which should do
the trick. Not sure of other folks have suggestions.
