JRuby and Devise

[pfriedland]

Probably should tell newer Ruby devs, like me, to stay away from using JRuby with this tutorial and Composer script. If you can get past not having the better_errors gem, then you may be faced with JCE (java cryptography) issues when trying to use the sample app. Problems seemingly go away when using YARV 2.0. I also think the Devise developers state that multi-threaded usage with JRuby is not yet supported.

Thanks for the tip.
