Description

For certain PDFs where we use PDFBox to open a PDF, scan for defined dummy QR codes on it, and then replace the dummy with a real QR code, we either get the above error, or the process does not terminate.

A sample file TET_5_4xxx_GR_00_00_XX_14_F.pdf or TSA_5_BF2x_GR_-1_01_XX_09_F.pdf .
They both lead to the above problem.

Our own analysis so far is that it might be the same issue as mentionend in https://stackoverflow.com/questions/69237146/pdfbox-renderimagewithdpi-hangs-sometimes

 

For our company PMG Projektraum GmbH, Munich, Germany, this is an essential function. Currently users cannot download PDFs in most cases because of this: The download tries to add a QR code and never ends.

It could be that the QR code on these PDFs causes issues because it is in a certain layer. We observed that in Adobe Reader we see a QR Code but with or own viewer it is invisible:

This is TSA_5_4xxx_SH_XX_05_XX_03_F.pdf

where we have the same issues

Any idea, what this might be and how to solve it?
