Hello!
The following code works successfully in SSHD 2.8.0; but it fails in SSHD 2.9.0:
{code:java}
final ClientSession clientSession =
SSH_CLIENT.connect(pURI.toString()).verify().getSession();
System.out.println("clientSession.getSessionState(): " +
clientSession.getSessionState());
System.out.println("clientSession.isClosed() : " +
clientSession.isClosed());
System.out.println("clientSession.isClosing() : " +
clientSession.isClosing());
System.out.println("clientSession.isOpen() : " +
clientSession.isOpen());
System.out.println("before addPasswordIdentity: " + new
Date(System.currentTimeMillis()));
clientSession.addPasswordIdentity("deneme123");
try {
Thread.sleep(3000);
} catch (InterruptedException ex) {
Logger.getLogger(UBSSHDProcessProvider.class.getName()).log(Level.SEVERE, null,
ex);
}
System.out.println("clientSession.getSessionState(): " +
clientSession.getSessionState());
System.out.println("clientSession.isClosed() : " +
clientSession.isClosed());
System.out.println("clientSession.isClosing() : " +
clientSession.isClosing());
System.out.println("clientSession.isOpen() : " +
clientSession.isOpen());
System.out.println("before auth().verify(): " + new
Date(System.currentTimeMillis()));
clientSession.auth().verify();
{code}
The output and exception:

The attached Bitvise SSH Server shows that the connection has ended at
23:50.29, which is immediately after
{_}SSH_CLIENT.connect(pURI.toString()).verify().getSession(){_}.
I added _Thread.sleep(3000)_ to see if _ClientSession_ state changes. After 3
seconds sleep, client session is still open. But,
_clientSession.auth().verify()_ is terminated with timeout after 2 minutes.
