------------------------------------------------------------------
It should have had {{@JsonCreator}} annotation over {{public
SchemalessScan(String userName, String selectionRoot)}} and getter for
{{selectionRoot}} for proper serialization / deserialization. Also it's better
to annotate getter with {{@JsonProperty}} to indicate what for it is needed.
