  For JRuby, specify the version of Ruby in your `Gemfile` based on the version of JRuby your app uses.
  
  JRuby version `1.7.x` supports either `1.9` mode or `2.0` mode.
  
  - For `1.9` mode, use the following:
  
      ```ruby
      ruby '1.9.3', :engine => 'jruby', :engine_version => '1.7.25'
      ```
  - For `2.0` mode, use the following:
  
      ```ruby
      ruby '2.0.0', :engine => 'jruby', :engine_version => '1.7.25'
