Oliver Schmidtmer commented on PDFBOX-5283:
-------------------------------------------

Ok, in the file from[ 
https://github.com/mozilla/pdf.js/issues/10326|https://github.com/mozilla/pdf.js/issues/10326]
 the entries for 4, 5 and 6 all point to wrong objects.

"found wrong object number. expected [4] found [5]
found wrong object number. expected [5] found [6]
found wrong object number. expected [6] found [4]"

So I changed the {color:#57606a}findObjectKey{color} to return a corrected 
Object key, but to only replace the original entry if it was not valid. That 
seems to work for both files.

>          Components: Parsing
>    Affects Versions: 2.0.24, 3.0.0 PDFBox

> There seems to be an issue with xRef / object reading when parsing the 
> attached pdf.
> The PDF itself has for example two objects with the ref "8 0 R":
> One at position 1967 with a "/Content" entry.
> One at position 7782 without a "/Content" entry.
> Both are referenced in the XRef Table, so there seems to be something off. 
> Probably Acrobat, etc. are using the first object, while PDFBox is using the 
> second one.
