Note:

To troubleshoot things down, I enabled debug logs by this guide http://www.bahmanm.com/blogs/how-to-add-logging-to-a-clojure-project (with a little change made to fix the stdout settings, see http://stackoverflow.com/questions/23281667/error-cannot-log-with-log4j).

After that the logs for passed ssh-test look like:
19:22:39,746 DEBUG ssh:272 - Authentications that can continue: publickey,keyboard-interactive,password
19:22:39,746 DEBUG ssh:272 - Next authentication method: publickey
19:22:39,775 DEBUG ssh:272 - Authentication succeeded (publickey).

And the logs for failed rabbit-test look like:
19:22:42,247 DEBUG ssh:270 - Authentications that can continue: publickey,keyboard-interactive,password
19:22:42,248 DEBUG ssh:270 - Next authentication method: publickey
19:22:42,248 DEBUG ssh:270 - Disconnecting from n4 port 22

Now I will try to feed that nasty jsch with my publickey as appropriate and provide a feedback here.

Strange things, jsch fails even by the password auth. While I can ssh to the node by console using the same creds. Probably this is some issue specific only to my environment.
