Tilman Hausherr commented on PDFBOX-5606:
-----------------------------------------
The attached file [^819127-p1.pdf] throws "IOException: Stream closed". The
file has a messy content stream. parseNextToken() is closing the content stream
if an error occurs, but it sometimes calls itself. Because of the closed
content stream the method returns null, which is reported with the position.
Trying to get the position on a closed stream throws the exception.
> PDFTextStripper runs out of memory in 2.0.28 but not in 2.0.27 same code

> `8-K` from [https://investor.apple.com/sec-filings/default.aspx], but any 10+
> page pdf with a lot of text will work.
> I have attached profiler screenshots of the difference.
> Thanks in advance for your help.
