PDFBOX-4569 implements an on demand parser which might help. It is still under development but IMHO a huge step forward especially in cases like this

> Key: PDFBOX-4297
> URL: https://issues.apache.org/jira/browse/PDFBOX-4297
> Project: PDFBox
> Issue Type: Improvement
> Components: Parsing
> Reporter: Ralf Hauser
> Priority: Major
>
> Assume you get a 300+MB large pdf and need to know
> 1) the file names of embedded files if any
> 2) whether it is encrypted (symmetric or asymmetric)
> 3) certification level (and whether it is signed)
> This should not use more than 5 MB (extra) memory
>
> P.S.: seems to an exampe of https://pdfbox.apache.org/ideas.html "Handle large PDF files"
