Swagger schema not showing custom value of enum

I have created an enum which also stores a value

import com.fasterxml.jackson.annotation.JsonValue;

public enum AnimalType {
  DOG("dog"),
  CAT("cat"),

  private final String displayName;

  AnimalType(String displayName) {
    this.displayName = displayName;
  }

  @JsonValue
  public String getDisplayName() {
    return displayName;
  }

  @Override
  public String toString() {
    return displayName;
  }
}

I am creating enum in this way because the user will give me input dog or cat. The enum value is getting serialized and deserialized properly.

But the swagger.json is showing DOG and CAT in place of dog and cat. I don't want the user to see the internal enum name and since the schema will be used by the users, I want to display the dog or cat in the schema.

        "type" : {
          "type" : "string",
          "enum" : [ "DOG", "CAT"]
        },

I have tried using @JsonProperty annotation( like @JsonProperty("dog")), but that didn't solve the problem. Can you please guide me on how I can solve this problem?

Versions:
swagger: 2.0
jackson: 2.7.9

Test your code with

@JsonCreator
public static AnimalType fromString(String key) {
    return displayName == null
            ? null
            : AnimalType.valueOf(key.toUpperCase());
}

I tried various alternatives to make it work such as

public enum AnimalType {
  @JsonProperty("dog") DOG("dog"),
  @JsonProperty("cat") CAT("cat"),

or using @JsonCreator as suggested by @sercheo_87. But the schema was not showing the required value.

I found out that it is a bug in swagger-core. Taking a updated version of swagger helped me. Also they are backporting the changes to this version.
