I was able to reproduce this issue in our staging environment.
What happens is that if you configure more than 1 job for a certain gerrit event and the first triggered will fail - jenkins will fail to exand the gerrit-trigger-plugin parameters and will throw a 'ConcurrentModificationException'

Here is what I've found in the logs:

My guess is that it has to do with the fact that Jenkins runs different 'Run' (A particular execution of Job) classes in different threads, while the gerrit-trigger-plugin parameters are shared among those threads so maybe the lock mechanism between the threads is not working so well.
Anyway, I've opened a ticket for the guys from Jenkins. I'll follow up on it and see if we get any information.

This is blocked on where we failed to make CI post-merge jobs run so far. This may or may not be and instance of the issue.

This may also be related to and the somewhat strange voting behaviour we have.

Another example: https://gerrit.ovirt.org/#/c/80213/ broke master vdsm, but was not marked with check-merge -1.

What can we do to try and find the root cause for this?
