Thanks to Carl Hörberg and a new Heroku feature called buildpacks it is now easy to implement and run your own runtime on Heroku.

A buildpack to fast and easy use of JRuby on Heroku. Just create a Heroku app like this:

heroku create -s cedar --buildpack https://github.com/jruby/heroku-buildpack-jruby.git

It will download and unpack JRuby from jruby.org, install Bundler and run bundle install and then use your Procfile .
