I am getting this exception JDOM exception, what is causing this ? This worked fine in JDOM B7, but throws this in JDOM B9, Can you please help. 

Here's the code:
==============
   String DEFAULT_SAX_DRIVER_CLASS = "org.apache.xerces.parsers.SAXParser";
   org.jdom.input.SAXBuilder builder = new SAXBuilder(DEFAULT_SAX_DRIVER_CLASS);
   System.out.println("2");
  
   Document doc = null;
   String result = "OK";

System.out.println("MsgDispatch: Dispatch was called");
   try
   {
       
    if (args.length <= 0)
    {
        // Build the JDOM Document from default file
        String filename="C:/XMLExchange/Sample/addrfq.xml";
        System.out.println("3");
        doc = builder.build(filename);
        System.out.println("4");
    }
}
.....

Here's the Exception:
