I think xerces may be downloading from the internet, something the
LocalDTDResolver did not resolve.
How about putting a System.out.println() in the else{} of the
LocalDTDResolver to print the public Id, system Id.
public InputSource resolveEntity (String publicId, String systemId)

System.out.println("Could not resolve entity locally for
publicId :["+publicId+"] systemid :["+systemId+"]");
