XMLUNIT Namespace exception when comparing XML files

I have 2 XML files and when comparing them using XMLUNIT, I get the below exception.

Exception in thread "main" org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.

I am using the below code and it does not work as expected.

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

    factory.setValidating(false);

    try {
        factory.setFeature("http://xml.org/sax/features/namespaces", false);
        factory.setFeature("http://xml.org/sax/features/validation", false);
        factory.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false);
        factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);;
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    }

    XMLUnit.setTestDocumentBuilderFactory(factory);
    XMLUnit.setControlDocumentBuilderFactory(factory);
    XMLUnit.setIgnoreWhitespace(Boolean.TRUE);
    XMLUnit.setIgnoreComments(true);
    XMLUnit.setIgnoreAttributeOrder(true);

How can I make XMLUNIT ignore namespace validations?

Removing the 2 below lines made my code work as expecting.

factory.setFeature("http://xml.org/sax/features/namespaces", false);
factory.setFeature("http://xml.org/sax/features/validation", false);
