Investigation of JDK-8273383 found that NonblockingQueue had a previously unrecognized case where an ABA problem could arise. The client was updated to resolve the issue in JDK-8273383. However, the usage documentation for that class should be updated to discuss the issue.

There have also been a number of improvements made to NonblockingQueue as followups to that investigation. They should be checked for any additional suggestions for usage documentation updates.
