Note that the original test case does not and will not work -- Jackson requires definition of values that are referenceable, regardless of underlying data format.
This is done by using annotation
@JsonIdentityInfo
on type or property. Further, type to annotate needs to be POJO type (or, property value needs to be POJO type when used on properties).
But with these modifications, perhaps it should be possible to define POJO type that serializes as an integer number, and then use Object Id references?
This is challenging since representation in such cases is similar (by shape, that is, scalar datatype), and may not be something that can be supported. But this is not yet known to be a hard limitation.
