Re: [paho-dev] Paho Java client for MQTTv5 - Feedback / Suggestionsneede

["Mike Tran" <miketran@xxxxxxxxxx>]

As we implemented Automatic Reconnect feature
in the last Paho release, we had to introduce a new interface, MqttCallbackExtended.
I would like to start developing and running with Java 8. With Virtual
Extension Methods (Default Methods) in Java 8, new APIs can be added to
existing interfaces without breaking existing applications.

Hi All,
 
In anticipation of the MQTTv5 spec being
formalised we want to start looking at building a new Java client that
supports it. By building a new client from scratch, it allows us to take
advantage of a more moden JDK / JRE, lessons learnt from the past and of
course feedback from the community.
 
The rough idea currently is to build it in
a similar way to the existing mqttv3 client, i.e. use similar naming conventions
/ APIs (MqttAsyncClient etc..) but to make changes where appropriate so
that the development experiance for those wishing to use the library is
a lot easier. We could also bundle and wrap the existing mqttv3 client
inside the mqttv5 client so that in the event that the broker does not
support MQTT v5, the client can gracefully fall back to 3.1 or 3.1.1 whilst
still exposing the modern API.
 
Before I or anyone else starts development
on this though, we could really use your feedback and suggestions as to
how you would like to use the new client or how you think the existing
client could be improved!
 
So... If you can think of anything, please
tell us!

Kind regards,
