Sorry I couldn't identify the exact problem. It certainly is an odd error. The only other time I've seen it fail to find java.lang.Object was in this thread:
http://groups.google.com/group/Google-Web-Toolkit-Contributors/browse_thread/thread/7b2b7db63bbccdd6/fd3e1e17082d2f66?#fd3e1e17082d2f66 ... where I solved the problem by dumping my classpath and starting from scratch, basically. I never did find exactly what was causing the problem, but hopefully starting from scratch will work for you, too.
