[jira] [Resolved] (PDFBOX-4745) COSObjectKey.hashCode doesn't work
for generation numbers > 0
[ https://issues.apache.org/jira/browse/PDFBOX-4745?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Lehmkühler resolved PDFBOX-4745.
----------------------------------------
Resolution: Fixed
I've fixed the issue by shifting the number 4 times, so that generation numbers up to 15 are supported. IMHO that is more than needed although theoretically a generation number could by way much bigger <= 99999
