---------- BEGIN SOURCE ----------
import java.io.IOException;

} catch (SAXException | IOException | ParserConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Need to use the InputStream to load the file instead of directly loading with file on to inputsource.

like below,

Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new FileInputStream("test1#test.xml")));
