org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException: Fail to save

Question

I'm facing 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

Exception when try to write the each test scenario result(PASS or FAIL) into Excel sheet(.xlsx) after the each test scenario execution completion. I write the following two different modules for this purpose.

Please tell me where is the problem and how to resolve it..

//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);
      }
}

Answer 1

This can happen if a timeout occurs. I have code that works for a small dataset and throws this error with huge dataset.
