Cause

These log messages indicate a plugin has failed to unregister itself, either on startup or shutdown. There are several bugs that contribute to this behaviour, specifically:

• JIRA Fisheye Plugin -  JRA-24453 - Getting issue details... STATUS
• Behaviours Plugin - JBHV-79
• Script Runner - GRV-134

Resolution

If the workarounds in the provided bugs above do not resolve the issue, then we must identify the problematic plugin:

1. If the JIRA application is starting:
   1. Disable all user plugins by enabling Safe Mode ('Administration' -> 'Manage Add-ons' (or 'Find New Add-ons') -> 'Enable Safe Mode');
   2. Start enabling plugins one by one until the error message returns;
       Try to enable the plugin which was having problem first.
2. If the JIRA application is not starting:
   1. Backup and move all plugins out of the $JIRA_HOME/plugins/installed-plugins folder so that it is empty
   2. Start JIRA
   3. One by one, move each plugin back into the installed-plugins folder followed by a JIRA restart to confirm which plugin is causing the error
