How to get Json generated by MOXy to understand when a model is a number

To solve another problem, I switched from Jersey to EclipseLink MOXy to create JSON from the JAXB-generated object model (created by Sun JAXB 2.1.12). One difference that I noticed is that in an object model a numerical attribute is defined as

@XmlSchemaType(name = "nonNegativeInteger")
protected BigInteger count;

Jersey turns into

"count":1,

but moxy gives

"count" : "1",

How can I get MOXy to implement my number field, rather than quote it.

@XmlAccessorType(XmlAccessType.FIELD)
public class Root {

    @XmlSchemaType(name = "nonNegativeInteger")
    protected BigInteger count;

}

Demo

package forum11448966;

import java.math.BigInteger;
import java.util.*;
import javax.xml.bind.*;
import org.eclipse.persistence.jaxb.JAXBContextProperties;

public class Demo {

    public static void main(String[] args) throws Exception {
        Map<String,Object> properties = new HashMap<String, Object>(3);
        properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, "forum11448966/oxm.xml");
        properties.put(JAXBContextProperties.MEDIA_TYPE, "application/json");
        properties.put(JAXBContextProperties.JSON_INCLUDE_ROOT, false);
        JAXBContext jc = JAXBContext.newInstance(new Class[] {Root.class}, properties);

        Root root = new Root();
        root.count = BigInteger.TEN;

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(root, System.out);
    }

}


{
   "count" : 10
}
