file-io - org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException : Fail to save

Question

我面对org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException: Fail to save:an error occurs while saving the package : The part /docProps/app.xml fail to be saved in the stream with marshaller <br/> org.apache.poi.openxml4j.opc.internal.marshallers.DefaultMarshaller@7c81475b
在每个测试场景执行完成后尝试将每个测试场景结果(PASS 或 FAIL)写入 Excel 表(.xlsx)时出现异常。为此，我编写了以下两个不同的模块。

请告诉我问题出在哪里以及如何解决它..

//Method for writing results into Report
 public void putResultstoReport(String values[])
 {
      int j=NoofTimesExecuted;
      NoofTimesExecuted++;
      XSSFRow row = sheet.createRow(j);
      for(int i=0;i<values.length;i++)
      {
           XSSFCell cell = row.createCell(i);
           cell.setCellValue(values[i]);
      }
      try {
           System.out.println("Times:"+NoofTimesExecuted);
           wb.write(fileOut);
      }
      //fileOut.flush();
      //fileOut.close();
      }
      catch(Exception e) {
           System.out.println("Exception at closing opened Report :"+e);
      }

//Method for Creating the Excelt Report
 public void createReport()
 {
      String FileLocation = getProperty("WorkSpace")+"//SCH_Registration//OutPut//TestResults.xlsx";
      try {
           fileOut = new FileOutputStream(FileLocation);
           String sheetName = "TestResults"; //name of sheet
           wb = new XSSFWorkbook();
           sheet = wb.createSheet(sheetName);
           fileOut.flush();
           fileOut.close();
      }
      catch(Exception e)
      {
           System.out.println("Exception at Create Report file:"+e);
      }
}

如果发生超时，可能会发生这种情况。我有适用于小型数据集的代码，并在大型数据集上引发此错误。
