Headless on Fedora

Hello,
We have been running ManageEngine 6 on a Linux server (Fedora Core 5 with no X11 software) with Sun JDK5 installed, for ages now and suddenly ME wont start

We can't seem to start the ManageEngine using the trusty startApplicationsManager.sh script. We get a java.awt.HeadlessException error in the startup logs.

We're wondering if it is something to do with the fact that the ManageEngine can't start MySQL or summat and is trying to open a pop-up alerting us to the fact. Obviously its failing coz we have no windowing environment installed on our server?

All our MySQL props and drivers haven't changed so I'm a bit bemused as to why its suddenly decided to barf.

Any ideas??

Full stack trace now follows (apologies):
