      Workaround 1. If there is no "Caused by: java.lang.NullPointerException" in the exception stack

      Please check if there are forward proxy settings in JIRA (setenv.sh) and if they are set correctly. Please reference this article for further details on how to configure outbound proxy for JIRA: https://confluence.atlassian.com/jirakb/how-to-configure-an-outbound-http-and-https-proxy-for-jira-applications-247857187.html

      Workaround 2. Please notice – this applies to JIRA Software only. If there's JIRA Service Desk installed in the same instance as JIRA Software, the steps below will disable the Service Desk application

      Disabling the Analytics and the below add-ons will prevent this exception from being thrown. Please note it's a spurious exception that prevents analytics being thrown however will not affect how JIRA operates outside of sending analytics.
