Tilman Hausherr commented on PDFBOX-4080:
-----------------------------------------
We could create one scratch file and then reuse that one for all annotations,
this would save memory.
I looked at COSOutputStream... yes, that's one //TODO that was forgotten. Or it
is too tricky. The problem is that RandomAccess is not an InputStream or an
OutputStream. One would have to write some sort of wrapper...
About the rest... maybe. I don't really have a good thought to share.

> PDAbstractAppearanceHandler calls new COSStream(), this has a huge memory
> footprint (PDFBOX-3868 and PDFBOX-3852). We'd need to find a way to pass the
> document, or the document scratch file, or there will be trouble for files
> with many annotations, e.g. a long scientific document with many footnotes.
