Tilman Hausherr commented on PDFBOX-3940:
-
This regression first occured because of r187622 in PDFBOX-3923. One of the
offsets is incorrect (points within table) so exception is thrown and the
trailer is rebuilt. When rebuilding, this piece of code is hit:
{code}
// info dictionary
else if (dictionary.containsKey(COSName.MOD_DATE)
&& (dictionary.containsKey(COSName.TITLE)
|| dictionary.containsKey(COSName.AUTHOR)
|| dictionary.containsKey(COSName.SUBJECT)
|| dictionary.containsKey(COSName.KEYWORDS)
|| dictionary.containsKey(COSName.CREATOR)
|| dictionary.containsKey(COSName.PRODUCER)
|| dictionary.containsKey(COSName.CREATION_DATE)))
{
trailer.setItem(COSName.INFO, document.getObjectFromPool(entry.getKey()));
}
{code}
The "&&" was introduced in PDFBOX-3208 ("ModDate is mandatory for an info
dictionary"). In file 079977.pdf there is no /Info/ModDate. According to the
PDF specification /ModDate is not mandatory.
In PDFBOX-3208 the problem was that without the change there, an outline
dictionary was used as /Info because it had a /Title. I suggest check for
/Parent to decide it's not an /Info. If there are other dictionaries that have
items that are found in /Info then we'd have to add that as well.

The offset of the info object (1 0 obj) is 10641 in the table but is really at
10493.
