OpenAPI generator inheritance in version 5

Question

In previous version of open-api-maven-generator (4.3.1) I had inheritance with 1 field

 BaseField:
    type: object
    properties:
       id:
         type:integer

and used it to schemas where I needed it like

allOf:
    - $ref: 'BaseField'

And it was generated as inheritance

Schema extends BaseField

After version moved to 5. it becomes generated as injection

Schema {
// field of BaseField
Long id;
}

Is any way to back to inheritance?
