> PDFBox version 2.0.28 uses ever increasing memory, but version 2.0.27 does
> not.
> The test.pdf file I am using can be downloaded from Apple SEC filings page,
> `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.
