Looks good, Per. Thanks, Bengt On 2013-11-28 17:49, Per Liden wrote: Summary: When activating/deactivating the G1 pre-barrier all SATB queues are looped through and have their active state set accordingly. There is one queue per Java thread and a shared queue for all non-Java threads. The loop done to set the active state of all queues forgets to set the active state on the shared queue. I suspect this was missed because the logic in SATBMarkQueueSet::setactiveallthreads() is mixed with quite a bit of verification code. This patch also moves this verification code out into a separate function.

Testing done: jprt, kitchensink (10 hours), gcbasher (10 hours) http://cr.openjdk.java.net/~pliden/8029162/webrev.0/ https://bugs.openjdk.java.net/browse/JDK-8029162 cheers, /Per
