Exhausted available authentication methods - version 0.21.1

Hi,

Getting exception net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods while connecting to a RHEL 6.x box with MAC algorithms hmac-sha2-256 and hmac-sha2-512.

Able to connect through command line from the same box from where the java code is executing effectively ruling out issues with username/password or host keys.

Any help will be much appreciated. Thanks.
