Actually this isn't a problem with GWT RPC, but with the redirection 
that is performed from / to /ovirt-engine in the web server. You 
probably ended up with the following URL:

https://whatever/ovirt-engine/webadmin/webadmin/WebAdmin.html

This adds an extra "ovirt-engine" path element to the request, that the 
server side doesn't expect, so it assumes that there is a XSFR attach 
going on. Type an URL like this manually in the browser and it should work:

https://whatever/webadmin/webadmin/WebAdmin.html
