Emmeran Seehuber commented on FTPSERVER-414:
--------------------------------------------
I dont think so. At least other ftp clients (i.e. DirectoryOpus, FileZilla),
which issue MLSD commands, work. I think the problem here is that the directory
listing is transfered with the control connection, and gets "standard" control
connection status replies inserted into the last line (see DefaultFtpReply).
The workaround in the patch just fixed STAT enough to get it working with
Cyberduck. I have no clue if this is the correct fix.

> Key: FTPSERVER-414
> URL: https://issues.apache.org/jira/browse/FTPSERVER-414
> Project: FtpServer
> Issue Type: Bug
> Components: Server
> Affects Versions: 1.0.5
> Reporter: Emmeran Seehuber
>
> Some ftp clients (e.g. Cyberduck on Mac OS X) use the STAT command to list
> directores. The reply contains an invalid status code in the last line, which
> causes the ftp client to ignore the last line. So the last file in the
> directory does not show up in the ftp client listing:
