[jira] [Resolved] (PDFBOX-3536) IOException "Invalid dictionary,
found: 'r' but expected: '/' at offset 1148" on a valid PDF
[ https://issues.apache.org/jira/browse/PDFBOX-3536?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Lehmkühler resolved PDFBOX-3536.
----------------------------------------
Resolution: Fixed
Fix Version/s: 3.0.0
2.0.7
There was already an end of COSString detection in place. But it looked for another COSObject in the next line only. I've extended it to take the end of the COSDictionary as valid end for the previous COSString as well. Now, everything works fine.
[~sevaa] thanks for the report, [~tilman] thanks for the analysis
