Subject [jira] [Commented] (COMPRESS-299) Issue with a 7z encrypted file
Date Tue, 27 Jan 2015 13:37:35 GMT

    [ https://issues.apache.org/jira/browse/COMPRESS-299?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14293517#comment-14293517
] 

Tim Allison commented on COMPRESS-299:
--------------------------------------

[~sebb@apache.org], I think we do specify the encoding in the above test case for {{password}}.
 Where else do we need to specify it in the above?

[~ebourg], yes, thank you.  Apologies _if_ this is user error.  Jenkins is also making the
same error that I am and causing our builds to fail in both Java 1.6 and 1.7. :)
