Rename ObjectId _id to id in Jackson deserialization with Jongo and MongoDB

I just started working on a project using the play, jongo and MongoDB platform. The project was originally written in Play 2.1 with pojos with a String ID field annotated with both: @Id and @ObjectId. This will be saved in Mongo as an ObjectId, and when deserialized it will output id like: "id": "53fcb9ede4b0b18314098d10", for example,

Since switching to Jongo 1.1 and Play 2.3.3, the id attribute is always called "_id" when deserializing, I want the attribute to keep the field name, but I can not use @JsonProperty ("custom_name") as the Jongo @Id annotation does @ JsonProperty ("_ id") backstage.

import org.jongo.marshall.jackson.oid.Id;
import org.jongo.marshall.jackson.oid.ObjectId;

public class PretendPojo {

    @Id
    @ObjectId
    private String id;

    private String name;

    public PretendPojo() {
    }

    public PretendPojo(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
}

POJO, MongoDB, , RoboMongo

{
    "_id" : ObjectId("53fc984de4b0c34f1905b8ee"),
    "name" : "Owen"
}

, @Id.

{"name":"Owen","_id":"53fcbedae4b0123e12632639"}

PretendPojo :

   @Test
    public void testJongoIdDeserialization() throws UnknownHostException {
        DB database = new MongoClient("localhost", 27017).getDB("jongo");
        Jongo jongo = new Jongo(database);
        MongoCollection collection = jongo.getCollection("jongo");
        collection.save(new PretendPojo("Owen"));
        PretendPojo pretendPojo = collection.findOne("{name:   \"Owen\"}").as(PretendPojo.class);
        JsonNode json = Json.toJson(pretendPojo);
        assertNotNull(json.get("id"));
    }
