JSch is pretty much the only game in town. The error handling isn't as good as you'd like, but it has broad support for many important features including Kerberos authentication.

There is also the 'ganymed' library http://www.ganymed.ethz.ch/ssh2/ . A few year ago I compared the 'jcraft', 'ganymed' and the IBM (not open source but free-ish) libraries. Because of the IBM name, I expected the IBM ssh library to be the best but was disappointed because I kept getting unexplained random exceptions. The 'ganymed' library was easy to use but lacks some sophistication. In my simple non-exhaustive and non-formal test the jcraft product came out best. If you have time then these other products are worth testing but be careful of the IBM licence.
