Review Comment:
I dislike the need for all the annotations but Jackson insists on when you
go down certain paths.
If you put back the empty constructor as well as having the 2 param
constructor, you will possibly find that you don't need the JsonCreator and
JsonProperty annotations any more.
Jackson seems to prefer to use the no params constructor and to use
reflection to set the values on the fields.
