Have you installed any plugins recently to your instance? Check for this, as what @Christian mentioned, maybe this latest plugin is the source of your issues due to some incompatibilities.

You can remove them by performing the following:

1. Shutdown JIRA
2. Delete the plugin from$JIRA_HOME/plugins/installed-plugins
3. Delete the following as well:
   1. $JIRA_HOME/plugins/.osgi-plugins
   2. $JIRA_HOME/plugins/.bundled-plugins
4. Start JIRA back up.

Check whether you can log into JIRA. If you can, just let us know what is the latest plugin that you've installed, which may be causing this problem.

I'm not sure what you want. Can you log in successfully? I had the log entry once because of a problem in a custom plugin...Didn't have to do anything with JIRA though..
