The test is still failing after the fix of [JDK-8371502](https://bugs.openjdk.org/browse/JDK-8371502). I suspect the issue is in the `ReentrantLock` implementation but suggest to make one more update of this test to make it more clear. The test update includes the following changes: - update method `ensureReadyAndWaiting()`: - add `sleep(50)` at start of method - replace call to `rlock.hasQueuedThreads()` with call to `rlock.hasQueuedThread(vt)` - update method `checkStates()` to make it more stable and tracing output more clear Testing: - TBD: mach5 tiers 1-3
