>
> PDFBOX-5108 already added a check of the dictionary values of a compressed
> cross reference stream, but there are some more values which should be
> checked before parsing the stream. There is some room for reducing the memory
> footprint as well. PDFBox should calculate the object numbers during parsing
> the stream instead of creating a whole list of them before parsing the stream.
