OpenAPI, invalid @Override annotation in base class, in inheritance case.

[matadini]

Expected Behavior

Having several hierarchies of component inheritance described in the OpenAPI yml file, I want all classes to be generated correctly

Actual Behaviour

OpenApi generator adds the @Override annotation in the base class, which is the foundation for the inheritance hierarchy. The problem occurs when there is more than one inheritance hierarchy in the OpenAPI's yml file. It looks like the issue arises for the first found inheritance hierarchy.

Steps To Reproduce

1. Create simple app
2. Define example CRUD endpoints in OpenAPI yml file to generate API classes to implement
3. Define more than one, component inheritance hierarchy in yml file:

components:
  schemas:
    AnimalRequest:
      type: object
      properties:
        name:
          type: string
        valueType:
          type: string
      discriminator:
        propertyName: valueType
        mapping:
          catRq: '#/components/schemas/DogRequest'
          dogRq: '#/components/schemas/CatRequest'
    DogRequest:
      allOf:
        - $ref: '#/components/schemas/AnimalRequest'
        - type: object
      properties:
        dogProperty:
          type: string
    CatRequest:
      allOf:
        - $ref: '#/components/schemas/AnimalRequest'
        - type: object
      properties:
        catProperty:
          type: string

    AnimalResponse:
      type: object
      properties:
        name:
          type: string
        valueType:
          type: string
      discriminator:
        propertyName: valueType
        mapping:
          catRs: '#/components/schemas/DogResponse'
          dogRs: '#/components/schemas/CatResponse'
    DogResponse:
      allOf:
        - $ref: '#/components/schemas/AnimalResponse'
        - type: object
      properties:
        dogProperty:
          type: string
    CatResponse:
      allOf:
        - $ref: '#/components/schemas/AnimalResponse'
        - type: object
      properties:
        catProperty:
          type: string

4, gradle compileJava result: Generated AnimalResponse will contain @Override annotation:

    @Override
    public String getValueType() {
        return valueType;
    }

5. Problem occurse since 4.4.4
