[paho-dev] Paho Java client on vert.x

[Ian Craggs <icraggs@xxxxxxxxxxxxxxxxxxxxxxx>]

Just to say that I've been playing around with re-implementing the core 
of the Java client on Vert.x, keeping the external API the same.  I have 
some of the very basic tests working.  I'm thinking about putting the 
project into a Paho incubator repo.

The motivation?  Every time I've had to work on the Java client, I've 
found the threading model and class interactions to be over complicated 
and prone to implementation error.  There are several threads started 
for every client object created, more than should be needed.  In looking 
at the issues that I would like to fix for the 1.3 release:

https://github.com/eclipse/paho.mqtt.java/milestone/2

some of which are threading issues, I thought it might be easier to 
rewrite.   Or at least easier to maintain in the long run, while 
improving performance and hopefully reliability.

Now, I've done the first bit of Vert.x implementation, I probably ought 
to finish off the existing 1.3 release first.  Part of me is wondering 
just how long it would take to complete the Vert.x port though :-)

If anyone is interested in collaborating, let me know.
