Integer Enum in Array is not generated correctly in 3.0.7

There was very similar issue when generating Array of STRING Enums:
https://github.com/swagger-api/swagger-codegen/issues/7377

In 3.0.7 Swagger-Codegen version with 1.0.7 Swagger-Codegen-Generators the List is generated correctly for String type of Enum, but not for Integer type.
If I specify type of enum "integer" or "number", the enum values in Java Class still are generated as String values. See below
If I specify enum in yaml:

TbProductFilter:
  type: object
  properties:
    productType:
      type: array
      items:
        type: integer
        enum:
          - 0
          - 1
          - 2
          - 3

Enum in Java Class:

public enum ProductTypeEnum {
    _0("0"),
    
    _1("1"),
    
    _2("2"),
    
    _3("3");

    private Integer value;

    ProductTypeEnum(Integer value) {
      this.value = value;
    }

    @Override
    @JsonValue
    public String toString() {
      return String.valueOf(value);
    }

    @JsonCreator
    public static ProductTypeEnum fromValue(String text) {
      for (ProductTypeEnum b : ProductTypeEnum.values()) {
        if (String.valueOf(b.value).equals(text)) {
          return b;
        }
      }
      return null;
    }
  }
  @JsonProperty("productType")
  @Valid
  private List<ProductTypeEnum> productType = null;

And ofcourse the code doesn't compile - values are strings, but everywhere else Integers are expected.

Start with the provided OpenAPI YAML and inspect the generated Java ProductTypeEnum for the array property. Compare integer enum handling with the referenced string-enum issue and trace the generator templates or entry point responsible for Java enum values. Done means integer enum constants compile with integer values while preserving the expected generated behavior.
