 * any other processing of the route occurs. The preprocessing chain is terminated 
 * if an exception is thrown.  In fact, if a Preprocessor throws an exception, the rest of 
 * the Preprocessors in the chain are skipped along with the entire route.  If an exception
 * occurs in a Preprocessor, Postprocessors are not called either.  However, MessageObservers
 * are.
