HSSFSheet error when creating

[Jonathan Cowherd <jo...@genscape.com>]

When I load the attached file, I get a bizarre exception, which I can't
explain.  It lools like it attempts to set Properties from some sheets
(which I don't care about, just data).

<code>
public HSSFWorkbook loadFile(String file) {
  HSSFWorkbook iworkbook = null;
    try {
      InputStream idocument = new FileInputStream(file);
      log.debug("File exists, reading...");
      POIFSFileSystem idata = new POIFSFileSystem(idocument);
      log.debug("File " + file + " read.");
      iworkbook = new HSSFWorkbook(idata);
      log.debug("Excel Workbook found.");
      idocument.close();
    } catch (FileNotFoundException e) {
      log.fatal("File " + file + " can not be found.");
    } catch (IOException e) {
      e.printStackTrace();
      log.fatal("File or workbook " + file + " can not be read.");
    }
    return (iworkbook);
}
</code>

Should I attempt to force an encoding?  Can I bypass that step?
