ExamXML.compareXMLString(s1, s2) 行中的异常；

片段代码是

static public void main(String[] argv) throws IOException {

    String s1 = readFile("src/main/resources/file1.xml");
    String s2 = readFile("src/main/resources/file2.xml");

    String s = ExamXML.compareXMLString(s1, s2);
    System.out.println(s);

}

运行结果是：

我有这个问题的解决方案。

System.setProperty("javax.xml.parsers.SAXParserFactory",
        "com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl");

谢谢！
