Buggy source:
public static boolean save(List<AutoConversionType> beanList,File file) throws Exception {
  DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
  OutputStreamWriter output=null;
  try {
    DocumentBuilder builder=factory.newDocumentBuilder();
    builder.setErrorHandler(new ErrorHandler(){
      @Override public void error(      final SAXParseException exception) throws SAXException {

      }
      @Override public void fatalError(      final SAXParseException exception) throws SAXException {
        throw exception;
      }
      @Override public void warning(      final SAXParseException exception) throws SAXException {
        throw exception;
      }
    }
);
    Document document=builder.newDocument();
    Element root=document.createElement("String_Node_Str");
    document.appendChild(root);
    for (int i=0; i < beanList.size(); i++) {
      AutoConversionType bean=beanList.get(i);
      Element typeNode=document.createElement("String_Node_Str");
      typeNode.setAttribute("String_Node_Str",bean.getSourceDataType());

      typeNode.setAttribute("String_Node_Str",bean.getConversionFunction());
      root.appendChild(typeNode);
    }
    if (document != null) {
      XMLSerializer serializer=new XMLSerializer();
      OutputFormat outputFormat=new OutputFormat();
      outputFormat.setIndenting(true);

Fixed version (ground truth):

  OutputStreamWriter output=null;
  try {

    builder.setErrorHandler(new ErrorHandler(){
      @Override public void error(      final SAXParseException exception) throws SAXException {
        throw exception;
      }
      @Override public void fatalError(      final SAXParseException exception) throws SAXException {
        throw exception;
      }
      @Override public void warning(      final SAXParseException exception) throws SAXException {
        throw exception;
      }
    }
);
    Document document=builder.newDocument();

      typeNode.setAttribute("String_Node_Str",bean.getTargetDataType());
      typeNode.setAttribute("String_Node_Str",bean.getConversionFunction());
      root.appendChild(typeNode);
    }
    if (document != null) {
      XMLSerializer serializer=new XMLSerializer();
      OutputFormat outputFormat=new OutputFormat();
