      Description

      ###@###.### 2004-04-14

      J2SE Version (please include all output from java -version flag):
        java version "1.5.0-beta2"
        Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b44)
        Java HotSpot(TM) Client VM (build 1.5.0-beta2-b46, mixed mode, sharing)

      Does this problem occur on J2SE 1.3.x or 1.4.x? Yes / No (pick one)
        no

      Operating System Configuration Information (be specific):
        WinXP

      Hardware Configuration Information (be specific):
        Dell Optiplex

      Bug Description:
        @Override triggers a compiler error as expected, but the message is not
        very helpful.

      Steps to Reproduce (be specific):
        During some code-generation I miss-implemented hashcode as follows:

        @Override
        public int hashCode(Object o)
        {
          int result = 0;
          result = result * 31 + ( (brand != null) ? brand.hashCode() : 0);
          result = result * 31 + ( (manufacturer != null) ? manufacturer.hashCode() : 0);
          return result;
        }

      The compiler prints the error message:
        src2\datamodel\coffee\Coffee.java:90: method does not override a method
        from its superclass
          @Override
         ^
        1 error

      It would have been helpfull if the error message included the
      name/signature of the method that @Override had been applied to e.g.:
      src2\datamodel\coffee\Coffee.java:90: method hashcode(Object) does not
      override a method from its superclass
        @Override
