I thought this was going to be easy. I'm trying to move a working GAE java app up to GWT 2.4.
But when I do, I see the following stack trace on the first RPC call to appengine. At least one other guy has seen this while doing same and posted a query at http://groups.google.com/group/google-appengine/browse_frm/thread/a78f4c443bd3b249<mhtml:{0C37AFDA-6C2E-445E-872B-6CCA8884F9E5}mid://00000000/> Any help, suggestions, or insight would be most appreciated! Thanks. The server is running at http://localhost:8888/<mhtml:{0C37AFDA-6C2E-445E-872B-6CCA8884F9E5}mid://00000000/> mozilla/5.0 (windows nt 6.0) applewebkit/535.1 (khtml, like gecko) chrome/14.0.835.163
