[jira] [Resolved] (PDFBOX-3948) NumberFormatException in
bfSearchForObjStreams
[ https://issues.apache.org/jira/browse/PDFBOX-3948?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Lehmkühler resolved PDFBOX-3948.
----------------------------------------
Resolution: Fixed
Fix Version/s: 3.0.0
2.0.8
The compressed object streams contains some unexpected newlines. Furthermore the root object is an conpressed object and those were simpky skipped in {{rebuildTrailer}}, so that I had to improve the method to process such objects as well
Thanks again [~tallison@mitre.org] and [~tilman] for the finding
