When using GWT-RPC, it pays to be as specific as possible. The reason is that in order to support polymorphism, the GWT-RPC compiler creates a custom serializer and deserializer for each subclass of your RPC return and argument types. This adds to compile time and the size of your application. Object is blacklisted for obvious reasons. I think Serializable is, too, but you don't want to do that, anyway, as there are an awful lot of classes that implement Serializable.
