Problem

After upgrading JIRA 

• You are unable to access JIRA
• You are unable to start plugins
• There are java.lang.NoSuchMethodError messages in the logs

The following appears in the atlassian-jira.log

java.lang.RuntimeException: javax.servlet.ServletException: java.lang.NoSuchMethodError: com.atlassian.jira.security.JiraAuthenticationContext.getLoggedInUser()Lcom/atlassian/crowd/embedded/api/User;
 
Caused by: javax.servlet.ServletException: java.lang.NoSuchMethodError: com.atlassian.jira.security.JiraAuthenticationContext.getLoggedInUser()Lcom/atlassian/crowd/embedded/api/User;
 
Caused by: java.lang.NoSuchMethodError: com.atlassian.jira.security.JiraAuthenticationContext.getLoggedInUser()Lcom/atlassian/crowd/embedded/api/User;

Diagnosis

• The following Add-ons has been confirmed to be incompatible and cause the above problems:

  • jira-workinghours-plugin-1.5.5

  • jira-calendar-plugin-2.1.11

  • ephor-for-jira-1.2.3

  • hipchat-for-jira-plugin-6.31.0

  • bugdigger-jira-plugin-2.5.1

  • whoslooking-2.1

Cause

JIRA changed to use a different class causing incompatibility by any Add-on still using the deprecated API.

Resolution

If you can access JIRA 

1. Open the Manage Add-ons page by navigating directly to:

   http://<jira-address>/plugins/servlet/upm

   Replace <jira-address> with the actual address from your JIRA instance.

2. Update or disable any add-ons displayed as Incompatible.
3. If the page above is not accessible and shows the same error, follow the steps under Resolution 2 below.

If the suggestion above does not work

1. Stop JIRA
2. Go to your the $JIRA-Home/plugins/installed-plugins directory

3. Rename the $JIRA-Home/plugins/installed-plugins directory to $JIRA-Home/plugins/installed-plugins2

4. Restart JIRA - This will re-create the the $JIRA-Home/plugins/installed-plugins directory but JIRA will start without any plugins
5. If the issue is no longer reproducible, Reinstall the add-on with the latest version through the Administration > Add-ons > Find new add-ons page.
6. You may later delete the $JIRA-Home/plugins/installed-plugins2 directory which is no longer in use. 

If the above steps do not resolve your problem

1. Compress a copy of the following directory: $JIRA-HOME/plugins/installed-plugins
2. Collect a file listing of the above directory showing permissions such as: ls -la in Linux
3. Generate a Support Zip, or zip the $JIRA-HOME/log & $JIRA-INSTALL/logs directory
4. Raise an issue with Atlassian Support, detailing steps attempted, and providing the above data for us to review.
