Symptoms

Immediately following an upgrade to the Universal Plugin Manager, the Universal Plugin Manager entirely disappears from JIRA

The following appears in the atlassian-jira.log:

Could not instantiate bean class [com.atlassian.upm.mac.HamletClientPacProxyImpl]: Constructor threw exception; nested exception is org.apache.http.conn.ssl.SSLInitializationException: Failure initializing default system SSL context

Diagnosis

This is typically seen when JIRA is used with a custom Java TrustStore.

Happens at very old version of UPM from several years ago.

Cause

The Universal Plugin Manager is trying to connect to Atlassian servers to poll for existing plugin licenses to make sure you're getting the plugins you've paid for. As this is somewhat sensitive information, it uses SSL to transmit to our servers. If the SSL component cannot be called, the UPM fails to load and is not part of JIRA.

Workaround

Roll the Universal Plugin Manager back to roll back the UPM to a known-good version. We have reliable reports that 2.9.3 will operate in this condition.

1. Stop JIRA
2. Remove the following files: <jira-home>/plugins/installed-plugins/atlassian-universal-plugin-manager-plugin-2.13.jar and <jira-home>/plugins/installed-plugins/plugin-license-storage-plugin-2.9.3.jar
3. Start JIRA
4. Upgrade Universal Plugin Manager to version 2.9.3

Resolution

• Address the issues that are preventing the SSL components from loading

• Ensure that if you've defined a custom truststore using the -Djavax.net.ssl.trustStore= directive, that you've also defined -Djavax.net.ssl.trustStorePassword= and -Djavax.net.ssl.trustStoreAlias= as appropriate.
