------------------------------------------------------------------
I'm able to run ExtractText on the command line with -Xmx15m with 2.0.27 and
2.0.28 using jdk20, which is pretty low. (I could retest with jdk8 if needed)
What really counts is if the memory usage would be different.
PDFTextStripperByArea hasn't been changed, but the parent class had a minor
change.

> 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.
