This allows Jackson to set all unmapped fields when deserializing but doesnt expose the setter to any users of our data model. } So if you have a non-modularized application or a modularized application with java.desktop on the module path, it's perfectly fine to let lombok generate the annotation by setting lombok.anyConstructor.addConstructorProperties=true, or to add the annotation manually if you are not using lombok.
