java.io.IOException: Unknown dir object c='>' cInt=62 peek='>' peekInt=62
Hello PdfBox-Team,
we have the following problem in our project:
When merging documents we get an exception for a certain document. That's why we updated the version of pdfBox to 3.0.1. Now we can merge the documents but we still get the error in the logfile.
We merge documents by using pdfMergerUtility.mergeDocuments();
Extract from the logfile:

We can't share the original document of our customer with you, but we could manipulate an empty pdf document by inserting the problematic object:
14 0 obj
<< /N >>
endobj
I attached the example pdf to my email.
Kind regards,
Ines

Hi,
This is a syntax error in the PDF. There should be another token after "/N".
