------------------------------------
Hi [~sebb]
Thank you for your idea, but mListDir returns an empty array on that server,
and mListFile(<filePath>) always returns null (the result of
sendCommand(FTPCmd.MLST, pathname) is 500).
I submitted a small PR with a fix which works on my side and tests were also OK:

> FTPClient::listFiles() doesn't include files with spaces for AS400

> Environment: AS400 ftp server
> Reporter: Dmytro Sylaiev
> Priority: Major

> For the FTP server on AS400 I got the different response size for
> FTPClient::listFiles() and FTPClient::listNames() (first one doesn't include
> file with spaces)
>
> TheOS400FTPEntryParser pattern is
> {noformat}
> private static final String REGEX =
> "(\\S+)\\s+" // user
> + "(?:(\\d+)\\s+)?" // size, empty for members
> + "(?:(\\S+)\\s+(\\S+)\\s+)?" // date stuff, empty for members
> + "(\\*STMF|\\*DIR|\\*FILE|\\*MEM)\\s+" // *STMF/*DIR/*FILE/*MEM
> + "(?:(\\S+)\\s*)?"; // file name, missing, when CWD is a
> *FILE{noformat}
> and the server response for LIST command
> {noformat}
> MYUSER 3 06/12/21 18:31:29 *STMF file with space.txt {noformat}
> doesn't match that regex.
