The issue is caused by:

java.lang.ClassCastException: com.atlassian.jira.user.BridgedDirectoryUser cannot be cast to com.atlassian.jira.user.ApplicationUser

But your stack trace does not indicate the location where that CCE actually occurs. But that panel comes from https://github.com/MeetMe/jira-gerrit-plugin/blob/master/src/main/resources/atlassian-plugin.xml#L227 so the class would have to be com.meetme.plugins.jira.gerrit.webpanel.GerritReviewsIssueAgilePanel

That class was a PR contribution ( #24 ), so I'm not familiar with the code. Perhaps @borgeorgiev has some further insight?

Will track this in #30.
