Java Jackson org.codehaus.jackson.map.exc.UnrecognizedPropertyException

I'm using Jackson to bind the JSON response to my class. Everything is fine unless there are more fields in my JSON response instead of my class definition. I hope Jackson ignores the fields that don't exist in my JSON response. This is due to the compatibility of future versions. If I add a new field, I don't want the previous version of the client to crash

Ideas?

ObjectMapper mapper = new ObjectMapper(); // can reuse, share globally
        PromoResponse promoResponse = mapper.readValue(r, PromoResponse.class);

resolvent:

You can place the @ jsonignoreproperties (ignoreunknown = true) comment on the promoresponse class
