We recently upgraded JIRA Data Center to 7.3.6 from 7.1.6. Prior to the upgrade, Jenkins Integration for JIRA was working correctly. Now, we are unable to install the latest version (2.3.2) of the plugin. The node we are working from will not release the cluster lock, and eventually freezes. In order to keep using the node, we need to stop JIRA on this node, and delete the jar from <shared-home>/plugins/installed-plugins.
Steps to duplicate:
Go to "Manage Add-ons"
