I used two different Thing :
1) the first implement the Thing Template MQTT (extension)
2) the second implement a Thing Template that was customization from Mqtt thing template
For both sample there is the same issue.
For both example I use only the Subscription.
My configuration is:
- windows 7 64bit
- thingworx 7.2.3-b48
- presistent provide H2
- java jre 1.8
- tomcat 8.0.36
