Description

Adding connect timeout for NET-399 changed the code to use socketFactory.createSocket() instead of createSocket(host, port).

As FTPSSocketFactory does not implement createSocket(), this means that the context socketFactory is not used, leading to:

java.net.SocketException: Unconnected sockets not implemented
        at javax.net.SocketFactory.createSocket(SocketFactory.java:104)
        at org.apache.commons.net.ftp.FTPClient._openDataConnection_(FTPClient.java:714)
        at org.apache.commons.net.ftp.FTPSClient._openDataConnection_(FTPSClient.java:549)

Fix is to implement the no-arg createSocket() method.
