[SPRING] - $ref is location dependent?

Should the location of the $ref affect the behavior of building classes?

In this first case, the class TransactionRequestSale extends TransactionRequest (as you would expect). The fields Amount and Type are created with getters/setters

TransactionRequestSale:
  description: A Sale request.
  allOf:
    - $ref: '#/components/schemas/TransactionRequest'
    - type: object
      properties:
        Type:
          type: string
        Amount:
          type: integer

but if the $ref is after the type, then TransactionRequest is used instead of the object, rather than extending the class. (ie the TransactionRequestSale class is created, but rather than the Amount and Type fields, it uses the fields from TransactionRequest)

TransactionRequestSale:
  description: A Sale request.
  allOf:
    - type: object
      properties:
        Type:
          type: string
        Amount:
          type: integer`
    - $ref: '#/components/schemas/TransactionRequest

The issue names no source files, tests, or entry points; begin by locating the Spring generator handling OpenAPI allOf schemas and reproduce both $ref orderings from the examples. Done means both forms generate TransactionRequestSale with the inherited TransactionRequest members plus the Amount and Type fields.
