What about subclassing UnsupportedOperationException like this:

--- cut ---

package gnu.org.classpath;

public class NYIException extends UnsupportedOperationException {
  static String nyi =
    "This method has not yet been implemented in GNU Classpath. Please " +
    "contact address@hidden if you want to use it.";

  public NYIException() {
    super(nyi);
  }

  public NYIException(String s) {
    super(s + "\n" + nyi);
  }
}

--- cut ---

Thus, we make sure the user always receives a helpful description and it is 
easy for VM implementations to replace the contact information by whatever 
else. I prefer grepping for class names to grepping for strings because there 
are no undetected typos in class names.


Cheers,

        Andy.
