Cause

This is caused by a bug in the UPM.

Resolution

To resolve this issue you need to upgrade Tomcat to version 6 or later. You can run through the following steps to get the UPM upgraded

  1. Shutdown Confluence
  2. Backup your database
  3. Find the UPM in your database and delete it
    1. select plugindataid,pluginkey,filename,lastmoddate from plugindata where pluginkey ilike '%upm%';
    2. delete from plugindata where plugindataid = 'number found in previous step';
  4. Migrate Tomcat to version 6
  5. Startup Confluence again, the older, bundled version of the UPM should now load.
  6. Upgrade the UPM from the UPM as normal, it should now work.
