[jira] [Resolved] (PDFBOX-3292) Error reading stream,
expected='endstream' actual='' in non-truncated files
[ https://issues.apache.org/jira/browse/PDFBOX-3292?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Lehmkühler resolved PDFBOX-3292.
----------------------------------------
Resolution: Fixed
COSParser#checkXRefStreamOffset simply checked if a dictionary can be found at the given offset. I rare case, such as the given pdfs, there is a dictionary but not the one we are looking for. Saying that, I've implemented an additional check to see if the dictionary at the given offset is the right one or not and now everything works fine.
