Say we have two initially empty j.u.c.ConcurrentLinkedQueue, clq1 and
clq2. If two threads offered to each queue individually at the same
time, followed by polling the other queue, is it possible for both
threads to observer the other queue as being empty ?
In other words:
Time Thread1 Thread2
0 clq1.offer clq2.offer
1 x=clq2.poll y=clq1.poll
Can both x and y be null ?
