JVM crashing while writing to XLSX file( POI&#

Question

JVM is crashing while trying to write to the .xlsx file. I am using POI(XSSF) for the same. The error location point in code is the write method--> workBook.write(fileOutputStream);

On Console I get..

A fatal error has been detected by the Java Runtime Environment:

Using OPCPackage did not fix the JVM crash for me but using WorkbookFactory did. If you look at the POI Busy Developers Guide they provide example of reading and writing the same Excel file.

File excelFile = new File("workbook.xlsx");

InputStream inp = new FileInputStream(excelFile);
Workbook wb = WorkbookFactory.create(inp);

FileOutputStream fileOut = new FileOutputStream(excelFile);
wb.write(fileOut);
fileOut.close();

Using Apache POI version 3.13, Java 1.8

The solution I've found for this, and I've been looking for a while, is to make sure you don't open your Workbook with the File which you use to open the FileOutputStream to save the Workbook. Instead, use a FileInputStream to open the Workbook.

Something like this will work flawlessly

        File inputFile = new File("Your-Path");
        this.inputStream = new FileInputStream(inputFile);
        this.opc = OPCPackage.open(this.inputStream);
        this.workbook = WorkbookFactory.create(opc);

...

        this.outputStream = new FileOutputStream(inputFile);
        this.workbook.write(this.outputStream);

Don't forget to close every opened stream and the OPCPackage.

None of the other solutions worked for me. I only needed readonly access to my Excel files, and setting the readonly flags worked for me:

Workbook wb = new XSSFWorkbook(OPCPackage.open(file, PackageAccess.READ));
Workbook wb = new HSSFWorkbook(new POIFSFileSystem(file, true));
