defaultValue attribute at enum object generate arbitrary json file

I have an enum object mapped in @Schema, that change arbitrary in each build

Sample

@Schema(defaultValue = "DELIVERY", name = "type",
      description = "Type of the shipping", example = "DELIVERY",
      enumAsRef = true)

"ShippingType" : {
        "type" : "string",
        "description" : "Type of the shipping",
        "example" : "DELIVERY",
        "default" : "DELIVERY",
        "enum" : [ "DELIVERY", "REVERSE", "TRANSFERENCE" ]
      },


"ShippingType" : {
        "type" : "string",
        "description" : "Type of the shipping",
        "example" : "DELIVERY",
        "enum" : [ "DELIVERY", "REVERSE", "TRANSFERENCE" ],
        "default" : "DELIVERY"
      },

Property default arbitrary order in object ShippingType in openapi json file

If i remove defaultValue, the json always the same

@Schema(name = "type",
      description = "Type of the shipping", example = "DELIVERY",
      enumAsRef = true)

plugin at pom.xml

                    </execution>
                </executions>
            </plugin>

Is that a way to fix this issue?

Start with the @Schema annotation and the swagger-maven-plugin-jakarta configuration shown in the report, then reproduce generation with prettyPrint enabled. Compare repeated OpenAPI JSON outputs for the ShippingType schema; done means the output is deterministic when defaultValue is present.
