Common issue after upgrading to GWT 2.1 from previous versions.
If you got this exception, probably you application has gwt-servlet.jar which belongs to the previous version.
Replace it or remove and let you environment to create it instead of the old one.
Worked for me.
Hoping it helps,
Dor

Thanks Dor, your solution helped me identify my problem. In my case, it was different version of Java the source was compiled with than the one I was trying to run it using GWT... :)
