Hi Konrad,
the maintainer of the Java client left the project for another
role, and so I have stepped in. I finished off the MQTT V5
implementation of the C client first, as that was my primary
responsibility.
I've been looking at the Java client for the past month or two,
with two goals:
1) a service release of the V3 client, answering some of the top
issues: https://github.com/eclipse/paho.mqtt.java/milestone/2
2) finishing off the V5 implementation.
I've put fixes in for a number of the highest priority V3 client
issues, so I plan on making a service release 1.2.1, soon.
Hopefully this week. There will still be some issues I want to
fix soon, but they could wait for a 1.2.2 or 1.3, as I want to get
the V5 client out too.
On the V5 implementation, I started by thinking I would finish
off the half-finished implementation. I realized that there were
a lot of tests missing, however, so I started filling in those
gaps, but it was difficult to fix the issues I found. I had
experimented with an implementation based on Vert.x, an
asynchronous event framework, and that looked promising, so now
I'm focussing on that implementation (keeping the external API
largely the same). It can be found in the vertx branch:
https://github.com/eclipse/paho.mqtt.java/tree/vertx
I hope to have a fairly complete V5 implementation in the next
two weeks. Writing the tests needed is as much work as the client
implementation. I'm open to any collaboration or contributions.
I've also added code coverage measurement with Jacoco for all the
packages, incidentally.

Hi.
I
would like to ask about when will paho Java API feature the
MQTT v5.
The
page:
https://www.eclipse.org/paho/clients/java/
says
that v5 is not supported and on the internet I found that
paho is planning to add v5 support to Java after C.
Some
sources mentioned that it is planned to happen around June
2018.
Since
half year has passed I wonder if this was already added to
Java API or is happening soon?
Best

Konrad
