Because you dont use the join() method in the WriteFuture. If you write
like this:
MinaConnectionObj.sessions.get(key).write(DataPacketObj).join();
the thread will wait until the packet has been sent. Otherwise you will
only send your packet to MINA but there is no guarantee that the packet
will be sent to the client right away.
