Affects Version/s: None
Fix Version/s: 3.0
FTPSClient does not provide any code to handle AUTH or ADAT, and does not provide support for handling a reduced buffer size provided by the server.
FTPSCommand defines int values for AUTH and ADAT, but if the integer values are used by client code, the value will be passed to FTPClient, which uses its own array of command strings, and FTPSCommand.AUTH will translate to "USER" and ADAT => "PASS", similarly for PBSZ, PROT and CCC.
These commands all need special handling, so should be dealt with by FTPSClient only.
FTPSClient can override the sendCommand(int) and sendCommand(int, String) methods in FTPClient which will help prevent problems.
Since most of these commands need additional special handling, there should be execNAME() methods for each.
FTPSCommand should be deprecated.
