When a user rolled back from a snapshot version the startup log seems filled with CNF Exceptions from the plugin not being loaded correctly.
Other things like the AdjunctManager is mentioned as well in the error log, so I am don't think it is the plugin's fault.

---------------------------------Old issue-----------------------------------------------------------
We are currently running Jenkins version 1.449 and Gerrit Trigger Plugin version 2.3.2.
The Gerrit Trigger plugin triggers Jenkins build jobs when a patch set is created in Gerrit code review. However, once the Jenkins build jobs complete, the plugin does not report the status back to Gerrit.
This has been happening quite often, like, once a week. Restarting the Gerrit Trigger does not fix the problem. So, we end up restarting Jenkins.
Any ideas on what is happening here and how we can resolve this issue and stop it from recurring?
