[Jersey] UnmarshalException for natural JSON format and namespace

Hi,

I am currently looking to add support for the natural JSON notation for
existing JAXB annotated classes. These classes are in a package
containing a package-info.java to declare an XML namespace.

As a test I added a package-info.java class to the Jersey example
https://maven.java.net/service/local/artifact/maven/redirect?r=releases&g=com.sun.jersey.samples&a=json-from-jaxb&v=1.9.1&c=project&e=zip
<https://maven.java.net/service/local/artifact/maven/redirect?r=releases&g=com.sun.jersey.samples&a=json-from-jaxb&v=1.9.1&c=project&e=zip>,
which contains the following:


@XmlSchema(namespace = "http://www.example.com/test", elementFormDefault
= XmlNsForm.QUALIFIED)
package com.sun.jersey.samples.jsonfromjaxb.jaxb;

import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;


When running the XML (de-)serialization tests all is fine:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><flights
xmlns="http://www.example.com/test"><flight><flightId>OK123</flightId><company>Czech
Airlines</company><number>123</number><aircraft>B737</aircraft></flight><flight><flightId>OK124</flightId><company>Czech
Airlines</company><number>124</number><aircraft>AB115</aircraft></flight></flights>


But for the JSON format tests I get the following error:

testGetOnAircraftsJSONFormat(com.sun.jersey.samples.jsonfromjaxb.MainTest)
Time elapsed: 0.641 sec <<< ERROR!

Is this supposed to work or can the natural notation not be used when
there is a namespace declared?

Thanks,
Guy
