Gary,

Ah yes, I think I can see what's happening here. There's an old out-of-date jar file hanging around in the lib directory: Strio-applet-0.1.4.jar.

The script you're running is being real clever and searching for all the jars in this directory at start-up time. I hadn't realised it did this - deleting this jar should solve your problem.

Cheers
Paul
