I couldn't figure out the reason why I was getting an auth cancel
exception, because JSch swallows its JSchAuthCancelException, instead
setting a boolean auth_cancel=true and throwing a generic JSchException
long after the fact.
In the patch below, I attach the JSchAuthCancelException to the
JSchException; this displays the reason for the AuthCancelException
("password", "keyboard-interactive", "publickey") in the stack trace,
which helps a lot.
