I'm trying to run Google's WebmasterToolsClient Java sample code [code.google.com], but am getting the stack trace shown at the bottom of my post.

I've tried running the code on Windows XP and Mac OS X, but both OS's get this problem. I'm using gdata-1.40.3 and have tried 1.5 and 1.6 JVMs.

Can anyone get this code running or suggest how to resolve the issue?
