It looks like we hardcode the old “remote://“ protocol in RemoteDomainConnectionService rather than the new http-remoting protocol, so it is a bug. I am not sure if that is something we should attempt to negotiate explicitly, or to make the <remote> element take a ‘protocol’ attribute?

This ^^ seems to be the real error. Try removing “-server” in the jvm-options.
