FtpFileObject.children may be an EMPTY_FTP_FILE_MAP if the last ls() returned empty collection. This is the case for the move untitled36/src/com/test/Base.as -> untitled36/src/Base.as:

> CWD /opt/lampp/htdocs/ftp_root
250 Directory successfully changed.
> RNFR untitled36/src/com/test/Base.as
350 Ready for RNTO.
> RNTO untitled36/src/Base.as
250 Rename successful.
> PWD
257 "/opt/lampp/htdocs/ftp_root"
> CWD untitled36/src/com/test
250 Directory successfully changed.
> PORT 192,168,0,112,51,217
200 PORT command successful. Consider using PASV.
> LIST

226 Directory send OK.

(LIST returned no children)
