Missing JsonSubTypes in Swagger Code Gen for jaxrs-jersey

Below is the sample yaml with Inheritance and Polymorphism. While generating server stubs for JAXRS-JERSEY. Model objects doesn't contain @JsonTypeInfo and @JsonSubTypes . Is this supported in latest swagger-codegen-cli-3.0.5.jar ?

Run the supplied inheritance and polymorphism YAML through swagger-codegen-cli-3.0.5.jar with the jaxrs-jersey generator, then inspect the generated model objects. Done means the generated models include the expected @JsonTypeInfo and @JsonSubTypes annotations for the Pet, Cat, Dog, and Lizard schemas.
