I am seeing the same exception - I am testing the upgrade from GWT 2.6.1 to 2.8.1. I have a Web Application configured in Eclipse (Luna) to run DevMode - this same configuration worked under V2.6.1. If I deploy the war file I build with the new GWT libraries under Tomcat, I do not have a problem. It is only when I'm trying launching thru Eclipse.
