Since JDK-8344773, there is an occasional stall when running some MultiJVM modes of SPECjbb2015. In the commit of JDK-8344773, the array of WorkQueue increased from 2^6 to 2^9 for shared queues. If we change this back as 0001-Original-size-of-queue-capacity.patch, the stall will disappear. But it does not help if we break out the loop of awaitWork for shared queue as 0001-Prevent-parking-for-shared-work-queues.patch. So it is unclear about the relation of the increase of capacity and the stall.
