Oliver Mannion commented on PDFBOX-4521:
----------------------------------------
Thank you [~tilman] for a super fast fix! š
I've verified org.apache.pdfbox:pdfbox:2.0.16-20190420.123304-37 from
[https://repository.apache.org/content/groups/snapshots/] can parse
[^Editathon_cheat_sheet_(EN)_MetaDefender.pdf] We'll have to upgrade to that
version from pdfbox 2.0.6 (which we are still using because ofĀ
org.apache.tika:tika-parsers:1.16) or backport the fix if we can'tĀ upgrade.
I'll raise this with our vendor. I only had a quick look at the PDF spec, does
it consider a missing Info value from file trailer to be an incorrect PDF? I'm
still able to open it in a PDF viewer.

> spec|http://wwwimages.adobe.com/www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/pdf_reference_1-7.pdf]
> Ā the {{Info}} key is optional. PDFBox correctly handles the case when there
> is no {{Info}} key and no value is present, but in this case, the key is
> present but without a value.
