Reading through the stacktrace, there’s nothing that would indicate a directly Vaadin related problem (otoh, I’m not saying that it wouldn’t be). I see you already posted the same question with GAE’s user groups. I hope you’ll get your answer there.

As a sidenote, I have a hard time finding anything “loopback”-related with Google App Engine. And I can’t really think about anything that would be loopback-y in GAE anyways, so maybe you’re trying to use some code that isn’t even intended to be used with GAE in the first place.

I’d recommend you, unless you’ve already tried to do it, to try and deploy your application locally in a Tomcat or Jetty or something similar, and try to debug it from there.
