Given the following XML input:

<?xml version="1.0" encoding="UTF-8"?>
<root parenttool="aValue">
    <!-- COMMENT -->
</root>


If the following code is run:

import java.io.File;
import javax.xml.bind.Binder;
import javax.xml.bind.JAXBContext;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;

public class Demo {

    public static void main(String[] args) throws Exception {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document document = db.parse(new File("input.xml"));

        JAXBContext jc = JAXBContext.newInstance(Root.class);
        Binder binder = jc.createBinder();

        Root root = (Root) binder.unmarshal(document);
        root.setParentTool(null);
        binder.updateXML(root);

        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer t = tf.newTransformer();
        t.transform(new DOMSource(document), new StreamResult(System.out));
    }
}


The correct output should be:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root>
    <!-- COMMENT -->
</root>


But is currently (the parenttool attribute should have been removed):

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root parenttool="">
    <!-- COMMENT -->
</root>
