FTPClient.listFiles() does not work properly, if remote server speaks German
----------------------------------------------------------------------------
Key: NET-365
URL: https://issues.apache.org/jira/browse/NET-365
Project: Commons Net
Issue Type: Bug
Components: FTP
Affects Versions: 2.2
Reporter: Johannes Katelaan
If you are connecting to an FTP server that speaks German you will get German
language month names in result to a LIST command. For month names with
three-letter abreviations that are identical to the english versions (eg Jan)
everything works fine. For month names that are not identical to the englisch
versions (eg Dez instead of Dec) you will get FTPFile entrys without date/time
information. This is just annoying, but OK.
You get a real problem in March. The German abreviation is Mär, containing the
German umlaut character ä. File entries with a date in March will just be
dropped without further notice. I think this should be considered a bug.
The reason for this behaviour is the REGEX in UnixFTPEntryParser, which matches
only to month names containing "normal" letters:
{noformat}[a-zA-Z]{3}{noformat}
So the month name "Mär" will not match.
I fixed this by changing this part of REGEX to
{noformat}\\D{3}{noformat}
In REGEX there are two occurances of the not working part that have to be
changed.
