>             Project: Commons Net
>          Issue Type: Bug
>          Components: FTP
>    Affects Versions: 3.0.1, 3.1
>         Environment: Windows Vista Enterprise SP2
> Java SE 1.6
>            Reporter: Thomas Axelsson
>              Labels: LIST, REST, listFiles, offset, restart, setRestartOffset
>             Fix For: 3.2

>
> First setting a restart offset and then requesting a directory listing makes FtpClient
send REST, LIST. The correct behavior should be to send only LIST and send REST on the first
file transfer operation.
> Versions 3.1 and 3.0.1 of commons-net have shown this behavior in our software.
> Following is a minimal sample, tested with version 3.1:
> {code}
> package test;
> import java.io.PrintWriter;
> import org.apache.commons.net.PrintCommandListener;
> import org.apache.commons.net.ftp.FTPClient;
> public class Test {
> 	public static void main(String[] args) throws Exception {
> 		FTPClient client = new FTPClient();
> 		client.addProtocolCommandListener(new PrintCommandListener(
> 				new PrintWriter(System.out), true));
> 		
> 		client.connect(Server.ip);
> 		client.login(Server.username, Server.password);
> 		
>         client.setRestartOffset(10);
>         
>         client.listFiles("");
> 	}
> 	
> }
> {code}
> Output:
> {code}
> 220 Welcome to FTP service.
> USER *******
> 331 Please specify the password.
> PASS *******
> 230 Login successful.
> SYST
> 215 UNIX Type: L8
> PORT 10,43,92,50,230,56
> 200 PORT command successful. Consider using PASV.
> REST 10
> 350 Restart position accepted (10).
> LIST 
> 150 Here comes the directory listing.
> 226 Directory send OK.
> {code}
