Exception when parsing from InputSource

[W. Nathaniel Mills, III]

In the xerces.jar that ships with WSAD 5.1 (C:\wsad51\eclipse\plugins\org.apache.xerces_4.0.13\xercesImpl.jar (1,176,093 bytes), I've found the parser doesn't appear to handle the end of inputsource correctly, when it is constructed from a String, throwing an exception where the line number is -1.  I've coded a workaround, but wondered if this is known and fixed, or if there is a better way to deal with this issue.

public void instantiateFrom(String strXML, ArrayList retList)
  throws XYZException {

 

  StringReader reader = new StringReader(strXML);
  InputSource inputSource = new InputSource(reader);

 

  m_List = retList;
  m_Parser.setContentHandler(this);
  m_Parser.setErrorHandler(this);
  try {
    m_Parser.parse(inputSource);
  } catch (SAXParseException e) {
   // handle end of file
   if (e.getLineNumber() != -1) {
     throw new XYZException(formatSAXParseException(e), e);
   } // else expected case due to reaching the end of the string
  } catch (SAXException e) {
    throw new XYZException(e.getLocalizedMessage(), e);
  } catch (IOException e) {
    throw new XYZException(e.getLocalizedMessage(), e);
  }
}
