A DESCRIPTION OF THE PROBLEM :
https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ConcurrentLinkedQueue.html
https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ConcurrentLinkedQueue.html
Observation: :Link on above pages to the fast non blocking algorithm research paper is missing and broken...

Actual link to update: https://www.cs.rochester.edu/~scott/papers/1996_PODC_queues.pdf

Note that this link is correctly mapped in JDK 13 doc though:
