Please use AbstractDispatchServiceImpl.

@Deprecated
public abstract class AbstractDispatchServiceImpl
extends RemoteServiceServlet
implements DispatchService

This is the server-side implementation of the DispatchService, for which the client-side async service is DispatchServiceAsync.

This class is closely related to AbstractDispatchImpl, in theory the latter wouldn't be needed, but we use it to workaround a GWT limitation described in DispatchAsync.
