      implements IsSerializable

  Exception that will be passed to the `AsyncCallback.onFailure(Throwable)` method when an incompatibility is detected between a `RemoteService` client and its corresponding `RemoteService` server.

  The correct response to receiving an instance of this exception in the `AsyncCallback.onFailure(Throwable)` method is to get the application into a state where a browser refresh can be done.

  This exception can be caused by the following problems:

  - The requested `RemoteService` cannot be located via `Class.forName(String)` on the server.
  - The requested `RemoteService` interface is not implemented by the `RemoteServiceServlet` instance which is configured to process the request.
  - The requested service method is not defined or inherited by the requested `RemoteService` interface.
  - One of the types used in the `RemoteService` method invocation has had fields added or removed.
  - The client code receives a type from the server which it cannot deserialize.

  Note that on the client, the `Throwable.getCause()` always return `null`.
