JENKINS-55342 added hashtag support. This is causing a Null Pointer Exception:

Going back to 2.40.0 we do not have this issue, it is present in 2.41.0, 2.41.1 and 2.42.0.

Context: Upgrading a Jenkins 2.401.3 installation with gerrit-trigger 2.39.1, saw this issue with 2.42.0. Reverting to 2.40.0 is okay.
Gerrit version is 3.11.0

Looking at line 527 (https://github.com/jenkinsci/gerrit-trigger-plugin/blob/master/src/main/java/com/sonyericsson/hudson/plugins/gerrit/trigger/hudsontrigger/GerritTriggerParameters.java#L527) appears to link it with the Hashtag feature

  Just to add - upgrading Jenkins to current LTS - 2.492.1, on AWS Linux 2023 (Fedora-based) via the RPM (baseurl=https://pkg.jenkins.io/redhat-stable)
  
  Also to clarify, we do not use Hashtags in our Gerrit commits.

  Comparing some other environments we have, the plugin itself is working in certain combinations:
  
  
  
  Jenkins
  Plugin
  Comments
  
  
  2.440.1
  2.42.0
  Works
  
  
  2.482
  2.41.1
  Works
  
  
  2.492.1
  2.40.0
  Breaks on higher versions of the plugin

  Can it be related to removing commons-compress from Jenkins Core?
  https://github.com/jenkinsci/jenkins/pull/9958 - from https://issue-redirect.jenkins.io/issue/73355 
  2.482 still contained commons-compress, but 2.492.1 does not.
  Previous LTS, 2.479.3, also works.
  
  So has JENKINS-73355 broken gerrit-trigger?
