[jira] [Commented] (TIKA-903) NPE thrown with password protected
Pages file
[ https://issues.apache.org/jira/browse/TIKA-903?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13263784#comment-13263784 ]
Nick Burch commented on TIKA-903:
---------------------------------
This file certainly isn't protected using regular zip passwords or similar, there's something very odd instead. It's enough to break unzip listing....
$ unzip -l testPagesVariousPwdProtected.pagesArchive: testPagesVariousPwdProtected.pages
