422 Unprocessable Entity on Restlet ClientProxy and GAE Server

[kerbymart]

This may be a bug that when a GWT uses ClientProxy to communicate with a Restlet Application hosted in a different server that allow Cross-domain access (CORS), it is always throwing Error '422 Unprocessable Entity' on every request from the ClientProxy.

Closing this issue as the GWT edition has been removed in 2.7 branch.
