Resolution:
There are the following alternatives to address this error:
Solution 1
Stop your JIRA instance.
In your JIRA server file system, browse to: JIRA_HOME/plugins/installed-plugins
Search for the UPM (Universal Plugin Manager) plugins JAR file, and move the JAR file to a different folder.
The name of the JAR file may be prepended with a number, such as:
846688264762062110.atlassian-universal-plugin-manager-plugin-2.7.6.jarStart your JIRA instance. (Now, the instance will start with the plugin uninstalled.)
Wait a while to complete the startup, then try to access your JIRA instance.
Move the .JAR file back to the installed-plugins folder
In case you have multiple versions of the UPM in place, make sure you only move the newest one back
Restart your JIRA instance
Solution 2
Stop JIRA.
Update the Universal Plugin Manager (Add-on Manager) by file replacement.
Start JIRA.
Solution 3
Stop your JIRA instance.
In your JIRA server file system, browse to: JIRA_HOME/plugins/installed-plugins
Search for the UPM (Universal Plugin Manager) plugin JAR file, and either move the file to a different folder or delete it.
The name of the JAR file may be prepended with a number, such as:
846688264762062110.atlassian-universal-plugin-manager-plugin-2.7.6.jarIn case you have multiple versions of the UPM in place, make sure you move or delete all them
Start your JIRA instance. JIRA will start with its bundled UPM (Universal Plugin Manager) version.
