Having the same problem on my Mac, 10.8, using the installed Java with the system. I cannot find bouncycastle anywhere on my system (locate, spotlight, etc.).

I solved my issue. Uninstalling Java completely (using the directions at http://stikine.wordpress.com/2012/03/02/howto-remove-java/) and then reinstalling it from Apple fixed it.
Prior to that, I did try installing Oracle Java 1.7, which wouldn't launch at all.
