I have a customer that uses a LOT of PDF files. They currently have 2
files that are failing when we try to render them.
The same files can be viewed with Acrobat Reader or Foxit PDF with no
errors reported.
From Acrobat Reader file info:
PDF Producer: PDFOut V3.8 – build 201 – Oct 28 2022
PDF Version: 1.6 (Acrobat 7.x)
The stacktrace makes me suspect that the file has an error in it's image
compression data - which other readers somehow ignore.
Any suggestions?
This is the exception trace from PDFBox 3.0.1
java.io.IOException: negative array index: -1 near offset 1
