I think it is (illegal). You should make one sub-interface of AValueProxy per type of AGenericEntityProxy that you'd use for its T type parameter; remove the type parameter (making AValueProxy no longer generic), and using @ExtraTypes (GWT 2.4 onwards) for polymorphism, listing the sub-interfaces you previously created.
It's probably possible to enhance RF to make this work, but for now I don't think RF is designed to handle such things.
