protocol gateway not work well while two conn using different protocol

[wsky]

Receiver.java

// for send message to lower buffer
    public ByteBuffer parseMessage(String protocol, Message message) {
        if (MQTT.equalsIgnoreCase(protocol)) {
            return MqttMessageIO.parseServerSending((MqttMessage) message,
                    (ByteBuffer) message.body);
        } else {
            return MessageIO.parseServerSending(message,
                    (ByteBuffer) message.body);
        }
    }

the convert should move to MqttMessageIO

(MqttMessage) message
