Jersey serializing Integer value by using JacksonJsonProvider

I have a web service in Jersey (2.9.1) and method that has to return a Integer value in XML or JSON depends on Accept header. I am using com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider as a JSON provider. I have moved to this one because of some issues with serialization of single element arrays. But now I have another problem: The returned value should looks like that in XML:

<integer>
   <value>1000083</value>
</integer>

and like that in JSON:

{"value":1000083}

but I receive this without single exception

{"fieldHandler": null}

Wrapper code:

@XmlRootElement(name = "integer")
@XmlAccessorType(XmlAccessType.FIELD)
public class IntegerWrapper {

  @XmlValue
  private Integer value;

  @SuppressWarnings("unused")
  private IntegerWrapper() {
  }

  public IntegerWrapper(Integer value) {
    this.value = value;
  }
}

Any ideas?
