Has anyone successfully used GWT-RPC in Vaadin7?

I’ve been fighting these servlet-mappings because I thought they were the cause of my issue after transitioning from GWT to Vaadin but then I stumbled across a Vaadin trac ticket which seems to suggest it doesn’t work correctly due to it being packaged in the wrong jar file.

Can anyone confirm for me whether it is possible at this point in time? I really want to stick with the GWT implementation for RPC as it works better for me.
