I encounter a case where I need to overwrite an Enum’s values but cannot change the code directly.

There is a deprecated package with an entity having an enum in its parameter list:

public class A {
    OldEnum member;

    public A(OldEnum member) {
        this.member = member;
    }
}

public enum OldEnum {
    // The values of @JsonProperty need to be updated
    @JsonProperty("value1")
    VALUE_1,
    @JsonProperty("value2")
    VALUE_2
}

I need to initialize an instance of class A to use this package. However, I find that:

• Simple initialization is not working here, because the Enum value is wrong.
• I cannot directly change the code of the Enum in the package as it was downloaded from Maven.

Now I cannot find a way to update the enum value. Does anyone have any idea for that?
