Error with Merge and Split Tools

[stevenchoong]

Hi guys, anyone here having issues with certain tools? I am not able to merge or split files (tools that will create a new brand files after these actions). This is the version I used:

Version: 3.2.1
Stirling-PDF-with-login.jar
OS: Windows 10
Error code: 500
Error Message: Unrecognised failure
This run failed for a reason Stirling does not yet recognise. The raw message is shown below.

This appears to be a v3.2.1 JAR packaging defect rather than a missing conversion program or a problem with both PDFs.

The exact Stirling-PDF-with-login.jar asset from v3.2.1 contains:

BOOT-INF/lib/jpdfium-natives-linux-x64-1.1.6.jar

but not jpdfium-natives-windows-x64-1.1.6.jar. Merge always uses JPDFium, and normal split operations use it too: merge implementation, split implementation.

The release workflow builds the downloadable JARs on Ubuntu without setting jpdfiumPlatforms; auto therefore selects the Linux native package. This matches open issue #8321, which reports NativeNotFoundException: No native binary for platform: windows-x64.

You can confirm the JAR and exception with:

java -version
jar tf Stirling-PDF-with-login.jar | findstr /I "jpdfium"
Get-Content .\logs\info.log -Tail 200 |
  Select-String -Pattern "JPDFium|NativeNotFound|merge|split|Caused by"

Version 3.2.1 requires Java 25, but an older Java would normally stop the application from starting at all. LibreOffice, Ghostscript, and QPDF are not required for merge or split.

Until a corrected JAR is published, use the Docker distribution or the Windows desktop package. For the server-with-login use case, Docker is the closer replacement. A source build can include all native packages with -PjpdfiumPlatforms=all. I would not assume a newer JAR fixes this until jar tf shows the Windows JPDFium native package.
