Created attachment 1190788 [details] bz1366939-test.patch Test case that demonstrates issue. The main issue is that unlock only wakes up one waiter: LockSupport.unpark(waiters.peek()); But LocalLock.lockForRemoteNode/ClusterHandler.lockFromCluster also only let one waiter at a time take the lock (which is then removed). Verified with EAP 6.4.11.CP.CR1 Retroactively bulk-closing issues from released EAP 6.4 cummulative patches. |
