I am not sure about this. Is this really required? We don't usually do this. I'd would be more inclined doing it, if we also addressed HSEARCH-1375 (or at least parts of it). I still don't understand why anything else than void handle(ErrorContext context) is needed. Also the renaming as suggested in HSEARCH-1375 should be done. Without these changes were are just putting lipstick on a pig.
