The error is caused by conflicting PDF-related JAR files in the project. First, check the userlib (and vendorlib, if used) folders for PDF dependencies such as pdfbox, fontbox, preflight, and xmpbox, and remove outdated or conflicting JARs. Then reinstall or update the Community Commons module from the Marketplace so that the correct dependencies are restored. As a final step, clean the deployment directory (Clean Deployment Directory) and rebuild the application.

 

Before deleting any JAR files, make sure to take a backup. It can also be helpful to remove the JARs one by one and test iteratively to identify which dependency is causing the conflict.

The latest version of Community Commons upgraded the dependency on pdfbox.jar. It looks like you have an older version of this in your userlib, and probably a newer version in your userlib or vendorlib. 

 

To fix this, check both the userlib and vendorlib for duplicate .jar files. If you find more than one with the same name, keep the one in vendorlib, or the highest version in userlib if there isn't one in the vendorlib. Pay particular attention to pdfbox-X.X.X.jar, but there could be other duplicates.

 

Once you have done this, go back to Studio Pro, go to App->Clean Deployment Directory, then rebuild your Mendix application. The problem should be fixed.

 

Good luck!
