Bug ID: 60977
Summary: Adding Properties create invalid .xlsx file
Product: POI
Version: 3.15-FINAL
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: XSSF
Assignee: dev@poi.apache.org
Reporter: ther...@cyberrock.net

Example created file
When adding a custom property, and invalid .xlsx is created.
using the java code:
try (final XSSFWorkbookworkbook = new XSSFWorkbook()) {
final POIXMLProperties properties = workbook.getProperties();
final POIXMLProperties.CustomProperties customProperties =
properties.getCustomProperties();
customProperties.addProperty("Project", project.getName());
workbook.write(outputStream);
try (final java.io.FileOutputStream fs = new
java.io.FileOutputStream("C:\\temp\\temp.xlsx")) {
workbook.write(fs);
}
When you try to open temp.xlsx in Excel, you get a "file is corrupted"
warning.
Upon disassembling the .xlsx file, I found the following incorrect custom.xml
file in docProps:
<?xml version="1.0" encoding="UTF-8"?>
<Properties
xmlns="http://schemas.openxmlformats.org/officeDocument/2006/custom-properties";
xmlns:vt="http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes";><property
pid="2" fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}"
name="Project"><vt:lpwstr>test</vt:lpwstr></property></Properties><?xml
version="1.0" encoding="UTF-8"?>
<Properties
xmlns="http://schemas.openxmlformats.org/officeDocument/2006/custom-properties";
xmlns:vt="http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes";><property
pid="2" fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}"
name="Project"><vt:lpwstr>test</vt:lpwstr></property></Properties>
Note the file seems to be written twice.
