JSON converts hexadecimal to decimal

If I am running the following java code with json version 20080701:

    String xmlString = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"><soap:Body><response><code>0x02FE0921</code></response></soap:Body></soap:Envelope>";
    JSONObject json = XML.toJSONObject(xmlString);

then I get a JSONObject which looks like this:

    {"soap:Envelope":{"soap:Body":{"response":{"code":"0x02FE0921"}},"xmlns:soap":"http://schemas.xmlsoap.org/soap/envelope/"}}

but if I am using json version 20090211 then the same code will get me a JSONObject looking like this:

    {"soap:Envelope":{"soap:Body":{"response":{"code":50202913}},"xmlns:soap":"http://schemas.xmlsoap.org/soap/envelope/"}}

Notice how the "code" is now in decimal (50202913) rather then remaining in hexadecimal (0x02FE0921).

It would appear that in this latest version of the JSON jar they don't assume a String as often as they use to...

Can this be changed? Can we somehow get the same behavior with the 2009011 version as we did with the 20080701 version?
