[OT] unit testing error-handling code

[D&J Gredler]

Has anyone found an easy way to unit test code that only runs when
Class.forName(String) throws a NoClassDefFoundError?

       try {
           c = Class.forName( className );
       }
       catch( NoClassDefFoundError e ) {
           // code to be tested
       }

It seems back asswards to be trying to *cause* this error :-)
