[jira] Resolved: (PDFBOX-872) ERROR
org.apache.pdfbox.filter.FlateFilter - Stop reading corrupt stream
[ https://issues.apache.org/jira/browse/PDFBOX-872?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Adam Nichols resolved PDFBOX-872.
---------------------------------
Resolution: Fixed
Fix Version/s: 1.4.0
Assignee: Adam Nichols
Patch looks good. Nice documentation. The only problem I see is that it removes a method which people may be depending on. I'm going to add that function back in and just default the boolean decrypt to "false" since the name of the function is "encryptData". I'm marking the old encryptData() method deprecated in favor of the new one. I just don't want to break compatibility with anyone's project without any warning. It will probably be removed in version 2.0, as people normally expect some API changes when the major version changes.
Patch committed (with small backwards compatibility addition) in revision 1037900.
