Tilman Hausherr commented on PDFBOX-4385:
-----------------------------------------
Don't know about MacOS, but Adobe Reader likely does parsing on demand which we
don't. Wouldn't it be easier if you just take that clients file and overwrite
"18446744073430152624" with "2 " (which is a guess) and also
tell him to complain to the creator of that PDF?
Alternatively, try this: in BaseParser replace the {{throw}} with {{return
COSNull.NULL}}.
