preferably

  static void raise () throw (Exception){ throw Exception(); }
                       ^^^^^^^^^^^^^^^^^
  "class 'Exception' is considered incomplete at this point, therefore
   cannot be used as an exception type in an exception-specification.

We do not have carret diagnostic yet, but we can improve on the error
message :-)
