Trouble forwarding ssh traffic: Bad packet length 1141944966. Disconnecting: Packet corrupt

[Chris Austin]

Are there any known problems with establishing an ssh connection through a
port forwarded by ClientSession.startLocalPortForwarding? Openssh is
reporting the following after a few lines of output:
Bad packet length 1141944966.
Disconnecting: Packet corrupt

This is using mina-core 2.0.7 and sshd-core 0.9.0
Steps to reproduce:
* build the attached maven project
* java -jar target/sshforward-1.0-jar-with-dependencies.jar <ssh host>
* ssh -p 10022 <user>@localhost
* run 'w'


package test;

import java.io.Console;
import org.apache.sshd.ClientSession;
import org.apache.sshd.SshClient;
import org.apache.sshd.common.SshdSocketAddress;
import org.apache.sshd.common.forward.DefaultTcpipForwarderFactory;

public class ForwardSsh {
    public static void main( String[] args ) throws Exception {
        String host        = args[0];
        int    port        = 22;
        String fwdHost     = "localhost";
        int    fwdPort     = 10022;

        Console console = System.console();
        String  user    = console.readLine("User: ");
        String  pass    = new String(console.readPassword("Password: "));

        SshClient client = SshClient.setUpDefaultClient();
        client.setTcpipForwarderFactory(new DefaultTcpipForwarderFactory());
        client.start();

        ClientSession session = client.connect(host,
port).await().getSession();
        session.authPassword(user, pass);

        SshdSocketAddress localAddr  = new SshdSocketAddress(fwdHost,
fwdPort);
        SshdSocketAddress remoteAddr = new SshdSocketAddress(host, 22);
        session.startLocalPortForwarding(localAddr, remoteAddr);

        System.out.printf("Forwarding %s:%d to %s:%d\n", fwdHost, fwdPort,
host, 22);
        console.readLine();
    }
}
