Description

Hi

So when using a discriminator I get a stack overflow. You can only see this when running in verbose.

Swagger Version: 2.2.3
Java Version: 1.8

I generate Java API code from this, but the failure happens in the parsing of the swagger document.

My Swagger:

Offer:
    type: object
    # Used in the parent object to distinguish which derived object is used.
    discriminator: offerType
    required:
      - "offerType"
      - "id"
      - "name"
      - "value"
      - "productType"
    properties:
      offerType:
        type: string
        example: "LimitedOffer"
      id:
        description: "Used internally in the database. Use this value for the delete endpoint."
        type: integer
        format: int64
        minimum: 1
      name:
        description: "The name of the product."
        type: string
        maxLength: 100
        example: "Samsung Galaxy S7"
      productType:
        $ref: "#/definitions/ProductType"
      description:
        description: "A description of the product offer."
        type: string
        maxLength: 200
        example: "The Galaxy S7's hardware design is largely identical to that of the S6; it retains its metal and glass chassis, but with refinements such as a squarer home button, and a thinner protrusion for the camera. Both models are available in black and gold colors; white, pink, and silver versions are available depending on market."
      inStock:
        description: "Is the product ex stock."
        type: boolean
        example: "true"
      value:
        description: "The value of points required to buy this offer."
        type: integer
        format: int64
        minimum: 0
        example: "10000"
      discountRate:
        description: "Optional percentage discount on this offer."
        type: number
        format: double
        minimum: 0
        maximum: 100
        example: 25.0
      expires:
        description: "Date on which the offer expires, and is no longer available."
        type: string
        format: date-time
        example: "2016-12-25T00:00:00.000+02:00"
      image:
        description: "Image base64 encoded data of the product on offer."
        type: string
        format: byte
        maxLength: 10000
        example: "iVBORw0KGgoAAAANSUhEUgAAAAYAAAAGCAMAAADXEh96AAAAA1BMVEX/8gA/aIoIAAAAC0lEQVR4AWMgGgAAACoAAdrhCd0AAAAASUVORK5CYII="

# Example of inheritance
  LimitedOffer:
    allOf:
    - $ref: '#/definitions/Offer'
    - type: object
      required:
        - "duration"
      properties:
        duration:
          description: "How long is this limited offer valid."
          type: string
          format: date-time
          example: "2016-12-25T00:00:00.000+02:00"
        availableFrom:
          description: "From when is the offer available."
          type: string
          format: date
          example: "2016-12-24"

The Stack Trace I get:

Research direction

Start by reproducing the verbose Java generation failure with the supplied Offer and LimitedOffer discriminator example, then trace the parsing and DefaultGenerator flow shown in the stack trace. The fix is done when this inheritance structure no longer causes infinite recursion or StackOverflowError during verbose processing, with the existing behavior preserved for valid discriminator models.
