Tilman Hausherr commented on PDFBOX-2527:
-----------------------------------------
What I mean is that you catch the exception in the nonSeq parser, and then only
use the old parser.
The attached PDF isn't just "bad" meaning that one developer hasn't applied the
specification to 100%. The PDF has trash at the end, maybe as the result of a
corrupted filesystem.
