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, the result is :* 
{noformat}
Exception in thread "main" java.lang.NullPointerExceptionException 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}
