These changes provide 2 things: - a minor bug fix for 6519647 (FTP PUT operation through HTTP proxy)- an overhaul of the FTP code and laying the bases of a future public FTP Client API.
That's why the code is separated between sun.net.ftp and sun.net.ftp.imlUltimately, what is in sun.net.ftp will become public either in java.net or java.net.ftp
