Andreas Lehmkühler commented on PDFBOX-4623:
I've found a fix for [^infinite-recursion.pdf]. [^loop_in_page_tree.pdf] and
[^poppler-43279-0.pdf] need a different fix therefore I've created a new
ticket for those issues. [^poppler-91414-1.zip-2.gz-53.pdf] doesn't trigger an
exception at all.
All I said is true for 3.0.0 and I'm afraid there won't be any fix for the
2.0.x-branch.
