> queueSendMap is a ConcurrentHashMap.
> At line 210:
> {code}
> if (!queueSendMap.containsKey(sid)) {
> queueSendMap.put(sid, new ArrayBlockingQueue<ByteBuffer>(
> SEND_CAPACITY));
> {code}
> By the time control enters if block, there may be another concurrent put with
> same sid to the ConcurrentHashMap.
> putIfAbsent() should be used.
> Similar issue occurs at line 307 as well.
