> `@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS)` – when you deserialize the
> `@class` value that appears in the JSON can be any class name and Jackson
> will load that class and try to create an instance.
> You should add a polymorphic type validator to your ObjectMapper that
> restricts which classes can be loaded at deserialization time.
