Replace org.apache.cxf.helpers.DOMUtils.writeXml(Node n, OutputStream os) missing in Apache CXF version 3.1.16

Question

I'm migrating from JBoss EAP 6.4 to EAP 7.1. I've updated Apache CXF from 2.7.14 to 3.1.16 but now I'm missing the DOMUtils.writeXml(Node n, OutputStream os) method. Which is the best way to replace it in a scenario like this?

SOAPMessage soapMessage = message.getContent(SOAPMessage.class);
SOAPBody env = soapMessage.getSOAPPart().getEnvelope().getBody();
ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
DOMUtils.writeXml(env, baos);
String soapBody = baos.toString();

I've replaced DOMUtils.writeXml(Node n, OutputStream os) using javax.xml.transform.TransformerFactory:

SOAPMessage soapMessage = message.getContent(SOAPMessage.class);
SOAPBody env = message.getSOAPPart().getEnvelope().getBody();
javax.xml.transform.dom.DOMSource source = new javax.xml.transform.dom.DOMSource(env);
StringWriter stringResult = new StringWriter();
javax.xml.transform.TransformerFactory.newInstance().newTransformer().transform(source, new StreamResult(stringResult));
String soapBody = stringResult.toString();
