Problem

When attempting to access Gadget activity streams or User Profile's activity stream for any user, it fails to load and throws an error similar to the following:

The following appears in the atlassian-jira.log:

Diagnosis

Environment

• Bamboo application links have been configured. 

Diagnostic Steps

• Bamboo application links are not working properly, and Bamboo data is not shown in JIRA's Development Panel, or is not updated.

• You may also see these types of NullPointerException errors in the logs:

Cause

A broken Bamboo application link causes the Activity Stream to fail to load entirely. When the Streams plugin attempts to retrieve Bamboo data, it hits into the NullPointerException and consequently is not able to load any data in the Activity Stream.

The NullPointerException at the moment is thought to be caused by a corrupted application link with Bamboo. 

Resolution

Delete and re-create the Bamboo application link, and confirm that Bamboo data can be shown in Development Panel and Activity Streams.

If the Bamboo application link is still broken and its features are unavailable, please raise a ticket with Atlassian Support to fix the application links.
