------------------------------
Seems highly related to NET-188.
> [FTP Client] Not listing files with 'invalid' date
> --------------------------------------------------
>
> Key: NET-190
> URL: https://issues.apache.org/jira/browse/NET-190
> Project: Commons Net
> Issue Type: Bug
> Affects Versions: 1.4
> Environment: FTP Gateway: Response: 331-httpiproxy2 FTP server
> (Version 1.9.2.4 - 2005/01/11 13:03:28) ready.
> FTP Server: Response: 215 UNIX Type: L8
> FTP Client: Jakarta Commons VFS over Jakarta Commons NET
> Reporter: Diego Souto
> Original Estimate: 3h
> Remaining Estimate: 3h
>
> When trying to list files in a FTP directory with two files returns 0
> FileObjects.
> With another FTP client.... response is:
> ftp> ls
> 227 Entering Passive Mode (212,163,35,155,160,40)

> ... so there are two files with date "FEBRUARY 29" (2008 is a leap year)
> When listing files with Jakarta Commons VFS over Jakarta Commons NET it
> returns 0 files.
> I revised Commons Net source and I found in
> 'org.apache.commons.net.ftp.parser.UnixFTPEntryParser' the following code:
> try
> {
> file.setTimestamp(super.parseTimestamp(datestr));
> }
> catch (ParseException e)
> {
> return null; // this is a parsing failure too.
> }
> So I guess maybe the timestamp parser is throwing a ParseException (perhaps
> it's guessing a incorrect year) and in this case is returning NULL so the
> calling class is ignoring these files with 'Feb 29' date.
> I think this behaviour is incorrect and must be fixed. If date is considered
> invalid it would throw an exception,... not simply ignore the file.
