Lost Application Link

Mark Cogan

After a system restart on OS upgrade (RHEL 7), the Application Link between Jira and Confluence stopped working. Jira seems to be running without issue, and Confluence started. But when trying to log into the Confluence admin page I get a 500 error as well. I suspect our reverse proxy configuration is off somewhere.

Red Hat has confirmed the jdk.tlk.maxHandshakeMessageSize parameter has been added to Java 8. The fix is to add the following in the setenv.sh file for Jira, Confluence, and any other applications running:

-Djdk.tls.maxHandshakeMessageSize=35000

Stop the application, edit the setenv.sh, then restart.

Is this indicating that our CA chain may be too long? Is there a way to increase the allowed handshake message size?

Mark Cogan

Nope! It's an update to Java 8 that adds a new configuration component:

jdk.tls.maxHandshakeMessageSize

So this is going to have to be modified in Jira to set a higher handshake message size.

-Djdk.tls.maxHandshakeMessageSize=35000

Stop the application, edit the setenv.sh, then restart.
