I'd be more concerned with what looks like metadata fields in the data stream. The top level 'abort' and 'more' attributes look like some kind of structured string which you may have to parse? Aside from that, you just need to model each Java object with the widest possible set of fields that will be sent from your external program. You don't have to worry if transmitted data has one or more of the fields missing, most JSON libraries will just deserialize a null in that case. Also, most of the JSON libraries will also allow you to specify that you want to ignore unknown incoming fields.

So between deserializing null for missing fields and ignoring extra fields, you should be good to go for your parse.
