--- Comment #2 from Tim Allison <talli...@apache.org> --- I agree with Dominik, we need more info. I'm not able to trigger this with plain Java: XSSFWorkbook workbook = new XSSFWorkbook(); XSSFSheet sheet = workbook.createSheet(); Row row = sheet.createRow(0); Cell c = row.createCell(0); c.setCellValue("this is a test"); String filename = "/xxx/test.xlsx"; java.io.OutputStream stream = new java.io.FileOutputStream(new java.io.File(filename)); workbook.write(stream); Do you have the same problem if you explicitly close the stream and close the workbook? -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
