Lyor Goldstein commented on SSHD-1040:
--------------------------------------

The reason for this is
{code:java|title=AbstractSession}
        synchronized (pendingPackets) {
            pendingWrites = sendPendingPackets(pendingPackets);
            kex = null; // discard and GC since KEX is completed
            kexState.set(KexState.DONE);
        }
{code}

> Hello,
> There's a bug for get the public key of a server from version 2.2.0.
> On the version 2.1.0, it works :
> *Code :*
> {code:java}
> SshClient client = SshClient.setUpDefaultClient();
> client.start();
> ConnectFuture connectFuture = client.connect("xxx", "xxx", 22);
> connectFuture.await(10000);
> ClientSession session = connectFuture.getSession();
> session.waitFor(Arrays.asList(ClientSessionEvent.WAIT_AUTH), 10000); 
> System.out.println(session.getKex().getServerKey().toString());
> {code}
> *Result :*
> {noformat}
> Sun RSA public key, 2048 bits
>  modulus: xxx
>  public exponent: 35{noformat}
>  
> *And with a higher version (example 2.5.1), the result is :* 
> {noformat}
> Exception in thread "main" java.lang.NullPointerException
>    at test.test.main(test.java:27){noformat}
> Line 27 is :
> {code:java}
> System.out.println(session.getKex().getServerKey().toString());
> {code}
