[Question][Java] Trying to generate classes for swagger with variable field names

Description

I need help generating classes for a third party swagger that I can't change (unless there is a way to easily find/replace the instances where this happens.)

Some parts of the definition are like this:

  Trip:
    description: The trip.
    type: object
    properties:
      journeysAvailableByMarket:
        description: Journeys per market.
        type: object
        properties:
          '*':
            type: array
            items:
              $ref: '#/definitions/AvailableJourney'

This ' * ' can return any string, and not have a ' * ' as a name, and can have multiple fields. So, for example, the response could be something like this:

	"journeysAvailableByMarket": {
		"EPA|COR": [
			{ ...
			}
		],
		"COR|EPA": [
			{ ...
			}
		]
	}

When I generate the classes this property becomes this:

  public static final String SERIALIZED_NAME_STAR = "*";
  @SerializedName(SERIALIZED_NAME_STAR)
  private List<AvailableJourney> star = null;

And so the deserialization doesn't work.
Is this possible to do with a swagger defined in this manner?

No repository file or test entry point is named. Start by reproducing Java generation and deserialization with the supplied Swagger schema, then trace how the wildcard property is represented; done means generated classes handle arbitrary keys such as EPA|COR and COR|EPA instead of treating * as a literal field.
