 // If a constant constructor contains an initializer, or an initializing
 // formal, for a final field which itself has an initializer at its
 // declaration, then a runtime error should occur if that constructor is
 // invoked using "new", but there should be no compile-time error.  However, if
 // the constructor is invoked using "const", there should be a compile-time
 // error, since it is a compile-time error for evaluation of a constant object
 // to result in an uncaught exception.
