Tilman Hausherr commented on PDFBOX-4080:
-----------------------------------------
Yes, passing {{PDDocument}} is a good idea because it would also solve another
recent problem with FreeText annotations:
[https://stackoverflow.com/questions/57450039/]
Here we'd need to put a chinese font into the acroform default resources.
Similar problem with the file here:
[https://gitlab.freedesktop.org/poppler/poppler/issues/6]
the FreeText annotation should use the font "Impact".
[~msahyoun] do you support that change?
[~gena77] why removal of the
{{appearanceDictionary.setRolloverAppearance(rolloverAppearanceEntry);}} line?

> 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.
