Connection with hmac-sha2-512 failed

[GoogleCodeExporter]

Connection to a OpenSSH server and a sshd Apache Mina with hmac-sha2-512 failed 
with message "Remote sent corrupt MAC"

What steps will reproduce the problem?
1.See java example below

Using an OpenSSH client works without errors

SSH Server version:SSHD 0.13.0 (Apache) / Openssh 6.7
Ganymed release: build261, 2013-08-09
Client platform: Windows 7 & Windows 8 (Java 7u71, 8u25)

PLEASE post a self-contained short java example.
public static void main(String[] args)
    {       
        try
        {
            Connection conn = new Connection("hostname","port");
            conn.setClient2ServerMACs(new String[]{"hmac-sha2-512"});
            conn.connect();
            boolean isAuthenticated = conn.authenticateWithPassword("username", "password");
            if (isAuthenticated == false)
                throw new IOException("Authentication failed.");
            Session sess = conn.openSession();
            sess.execCommand("whoami");
            System.out.println("ExitCode: " + sess.getExitStatus());

            sess.close();
            conn.close();
        }
        catch (IOException e)
        {
            e.printStackTrace(System.err);
            System.exit(2);
        }
    }
