[jira] [Comment Edited] (PDFBOX-5399) Object must be defined and must not be compressed object
[ https://issues.apache.org/jira/browse/PDFBOX-5399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17513035#comment-17513035 ]

----------------------------------------------------------------------
The real issue wasn't PDFBOX-5238 but the fact that the found object numbers are wrong. The offset of 1655 doesn't point to the object 55. Due to an off by two offset the object number of the correct object is parsed partially. I've improved the {{findObjectKey}} method so that such offsets to the offset are detected and the brute force search is triggered. In the end the problematic code of PDFBOX-5238 isn't relevant here anymore. ;-)
