@NotNull not generated when 'required' is declared in inheriting model

[gintautassulskus]

Description

Swagger-codegen does not generate the @NotNull annotation for the required property password of model UserRegister. The email property declared in model User is handled correctly, I can see the @NotNull annotation if front the corresponding method.

This has something to do with inheritance. The required field in the inheriting model (in this case - UserRegister) is ignored for both inherited (email) and new (password) properties.

Swagger-codegen version

2.2.3

Swagger declaration file content or url

definitions:

      type: object

        - password
      properties:
