excel - org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException in POI API after an .xls file is updated with Libre Office

Question

I am reading an Excel using POI api, I use the following code to read the excel file.

    public class ExcelWorkBook {

        private static ExcelWorkBook excelWorkBook = null;
        private static String filePath;
        private static XSSFWorkbook workbook;

        /**
         * This  constructor used to initialize the {@link ExcelWorkBook}
         * @throws IOException
         */
        private ExcelWorkBook() throws IOException {
            try {
                workbook = new XSSFWorkbook(getFile());
            } catch (FileNotFoundException ex) {
                Logger.getLogger(ExcelWorkBook.class.getName()).log(Level.SEVERE, null, ex);
            }
        }

        /**
         * This method create a new object {@link ExcelWorkBook}
         * @return {@link ExcelWorkBook}
         * @throws IOException
         */
        public static ExcelWorkBook getInstance() throws IOException {
            excelWorkBook = new ExcelWorkBook();
            return excelWorkBook;
        }

        /**
         * This method create a {@link FileInputStream}
         * @return {@link FileInputStream}
         * @throws FileNotFoundException
         */
        private FileInputStream getFile() throws FileNotFoundException {
          FileInputStream file = new FileInputStream(new File(filePath));
          return file;
        }
        .
        .
        .
        .

But its throwing following exception in a particular file which is created using MS Office 2010 and undated using Libre office. What could Be the problem. The Stack trace of exception is attached below

Answer 1

I had exactly the same exception after I edited with Libe Office a .xlsx file containing comments. The removal of the comments solved the issue.
