[jira] [Resolved] (PDFBOX-3936) IllegalArgumentException: root
cannot be null with truncated file (2)
[ https://issues.apache.org/jira/browse/PDFBOX-3936?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Lehmkühler resolved PDFBOX-3936.
----------------------------------------
Resolution: Fixed
Fix Version/s: 3.0.0
2.0.8
PDFBOX-3928 introduced an optimized brute force search for objects. It detects cut of objects by looking for the "endobj" marker. Unfortunately the attached pdf is cut of in the middle of that keyword. I've improved the algorithm by looking for "endo" instead of "endobj". We may improve the detection by looking for other end of object markers like "endstream" or braces depending of the kind of object but I'm not sure it it's worth to complicate the detection.
