> FTPSClient does not behave properly after issuing CCC (Clear Command Channel). Proper behaviour is to close SSLSocket, but keep underlying connection without SSL open.
> To achieve this, the SSLSocket should be created with "false", like this on line 255 (of FTPSClient v2.2)
> SSLSocket socket =
> (SSLSocket) ssf.createSocket(_socket_, ip, port, false);
> Furthermore, on sendCommand CCC, sslSocket must be closed before setting _socket = _plainsocket on line 493:
> _socket.close();
> _socket = _plainsocket;
> ...
> And finally, it is wrong to set socket factory to null on line 500 of the same method; this is set properly in exexPROT and should not be reset on CCC.
