Re: Error in MQTT Apache Camel route causes application to stop

[Claus Ibsen <cl...@gmail.com>]

Hi

I suggest to use camel-paho as Eclipse Paho is more active maintained
than the older FuseSource MQTT client library that camel-mqtt uses.

And you say you are using Camel 2.2.0, as that is a very old version,
then I assume you are using Camel 2.22.0 which is a new release.
Although Camel 2.23.0 is the latest version, so you can try upgrade to
that version also.

The JMS client works as excepted and whenever there is a failure in the initial connect or any further reconnect it is managed gracefully, so that the route keeps working. The problem comes with MQTT client, which causes a RuntimeException raised up to the top layer, so that the application stops.

This can be easily reproducer running a route with the MQTT broker down, it throws the exception to the Main class after the 10 seconds timeout elapses. I have checked the same code with the Paho client instead of plain MQTT client and it works fine, similar to JMS client I'm not sure if it is something realted to the internal implementation of the MQTT client or the wrapper of Apache Camel.
