Raminderjeet Singh commented on AIRAVATA-1433:
----------------------------------------------

Issue is if the SSH demon was not working or configured properly. Somehow SSHD 
was pointing to gsissh binary and was not working properly. JCraft was taking 
to UserAuthGSSAPIWithMICGSSCredentials class and failing at authentication 
method. In case of sshd configured properly and communication protocol is SSH 
then Jcraft calls UserAuthNone not  UserAuthGSSAPIWithMICGSSCredentials. We 
fixed the SSHD and the ssh communication is working fine. 

> NullPointerException to create a SSH connection
