The Polygon class is a JavaScriptOverlay type provided by Google and it does not have a no-arg constructor, so you can't use it with GWT-RPC. Other than that I assume you can't use JSO's on server side either (How should JSNI work on server side?) so it does not make sense to use them in a serializable class.
