Some comments :
- You can avoid to show will information if the isWillFlag is false so
there aren't empty fields to show
- avoid to show the will message payload as you are avoiding to show the
publish payload. I guess you are using an old version of the MQTT Netty codec
where will payload is a String but in the newer version it's a byte array like
publish payload
- having the CONNACK packet as well with the result code and if there is a
session is useful
- having PUBACK, PUBREL, PUBCOMP are useful as well with related packet-id
