Review comment:
When messagesForC is 0， consumer.sendMessages() will not be called, So
keyNumbers can not be update in the async callback of the
consumer.sendMessages(); And keyNumbers.decrementAndGet() == 0 may be not
true here.
I add logs in 'else if (currentThreadKeyNumber == 0) ', log is printed
sometimes.
