关于 Invalid byte 1 of 1-byte UTF-8 sequence
不知各位有没遇到过这样的问题呢？
问题描述：像一个url请求，获取得到的参数response如下

Java code

<?xml version='1.0' encoding='UTF-8'?><applyPrivilegeRet><formnum>100010</formnum><retn>-1</retn><desc>用户已经开通XXX套餐，不需要重复开通</desc><packages><opertype>1</opertype><privID>122216</privID><startdate>20120705</startdate></packages></applyPrivilegeRet>

通过以下代码解析该返回值，

Java code

    
    /**
     * 将xml输入流转成map对象
     * @param in -- xml输入流
     * @return -- map对象
     */
    public static Map toMap(InputStream in) {

        try {            
            SAXReader reader = new SAXReader();
            Document doc = reader.read(in);
            return toMap(doc.getRootElement());
        } catch (Exception ex) {
            throw new RuntimeException("解析xml成map对象异常", ex);
        } 
    }
     public static Map toMap(String xml) {
        ByteArrayInputStream sin = new ByteArrayInputStream(xml.getBytes());
        return toMap(sin);
    }

      public MyTest(String xml){
      toMap(response);
}                    

在两台linux服务器上，一台解析是没有任何问题的，另外一台出现java.lang.RuntimeException: 解析xml成map对象异常
