In JIRA version 4.4.4 bundling UPM 1.4.1 - the UPM will ask users to upgrade to incompatible JIRA 5.x plugins.
For example please see screenshot where the UPM is asking the user to install GreenHopper 5.9.x that will not work with JIRA 4.4.4
As a workaround for this please perform the following note it will require a JIRA restart:
- Go to this page and download the UPM .jar file for UPM 2.2
- Put that .jar into the folder [JIRA_HOME]/plugins/installed-plugins if there already is a UPM .jar in that folder remove it first.
- Restart JIRA, the new UPM should be in place.
