The following appears in the atlassian-jira.log:

Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
2012-09-23 20:37:42,167 main ERROR      [atlassian.event.internal.EventPublisherImpl] There was an exception thrown trying to dispatch event 'com.atlassian.plugin.event.events.PluginFrameworkStartingEvent@3bb6a350' from the invoker 'com.atlassian.event.internal.SingleParameterMethodListenerInvoker@4e64f6fe'.
java.lang.RuntimeException: Can't connect to X11 window server using 'localhost:10.0' as the value of the DISPLAY variable.


This seems to be a authenication issue when using the X11 forwarding option in Putty's settings and switching users before starting JIRA.


Current workaround is to disable X11 forwarding in Putty.
