    [ https://issues.apache.org/jira/browse/COMPRESS-237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13734479#comment-13734479 ] 

Stefan Bodewig commented on COMPRESS-237:
-----------------------------------------

I took the opportunity for a tiny refactoring in svn revision 1512161 - sorry I overlooked the "I'll commit it part" until I committed it myself.

Yes, additional tests would be great.

Thanks!

> TarArchiveOutputStream doesn't handle properly long link names, they are truncated silently in most cases.
> * In GNU mode a @LongLink entry should be created similarly to long names but with the 'K' type ({{GNU_LONGLINK}}) instead of 'L' ({{GNU_LONGNAME}})
> * In POSIX mode a pax header with the {{linkpath}} keyword should be added. This is already implemented for links containing a non ASCII character.
> * In the default ERROR mode no exception is thrown and the link is truncated.
> The logic for adding a pax header on non ASCII characters should probably be reworked, as it seems possible to have pax headers mixed with GNU @LongLink entries. I'm not sure this is desirable.
