Jongyeol Choi cceb99c359 Add exceptions for CONNACK's return code for MQTT 3.1 specification ... Motivation: http://public.dhe.ibm.com/software/dw/webservices/ws-mqtt/mqtt-v3r1.html#connack In MQTT 3.1, MQTT server must send a CONNACK with return code if CONNECT request contains an invalid client identifier or an unacceptable protocol version. The return code is one of MqttConnectReturnCode. But, MqttDecoder throws DecoderException when CONNECT request contains invalid value without distinguish situations. This makes it difficult for codec-mqtt users to send a response with return code to clients. Modifications: Added exceptions for client identifier rejected and unacceptable protocol version. MqttDecoder will throw those exceptions instead of DecoderException. Result: Users of codec-mqtt can distinguish which is invalid when CONNECT contains invalid client identifier or invalid protocol version. And, users can send CONNACK with return code to clients.		2014-10-13 07:27:33 +02:00
