Hi Rastko,

Just to clarify, are you running the validation on the file isartor-6-7-2-t02-fail-b_report.pdf ? It is not a part of the Isartor test suite. Would you please send the file as well?

Note also that 1.13.2 is a dev branch. The latest stable release version is 1.12.1.

Best regards,

Boris

Subject: [veraPDF-users] veraPDF throws Null Pointer Exception on file

Hello, everyone, 

I have another question. Running veraPDF (1.13.2) on the following file from the Isartor test suite (in 1-B mode) causes veraPDF to internally throw a Null Pointer Exception:

Misc\isartor-6-7-2-t02-fail-b_report.pdf

Here is the stack trace I see:
