By default, when serializing to JSON, json-lib set "" for new string properties (when null) and :null for objects, and per the JSON spec. However, this add lot of unnecessary noises to the json that the client see.
So, we need to add a ignoreNullFilter PropertyFilter that tells the json-lib to ignore properties with new values.
