Specifying JRuby Version in Bundler

I wasn't able to find a SO QA that could answer this.

I installed JRuby via rvm install jruby and then generated a new rails application. To allow for changing of the ruby version automatically via rvm, I discovered that Bundler allows you to add:

ruby '1.9.3', engine: 'jruby', engine_version: '1.7.12'

See here for reference. Since this is 1.3, I checked my Bundler version within my root app directory:

$ bundle -v
Bundler version 1.6.2

I'm assuming I have this functionality. Now, when I move onto adding this to Gemfile:

source 'https://rubygems.org'
ruby '1.9.3', engine: 'jruby', engine_version: '1.7.12'

gem 'rails', '4.1.1'
gem 'activerecord-jdbcsqlite3-adapter'

And then after running cd .. && cd app I received this issue:

RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore  /Users/benmorgan/Sites/sigma/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

Unknown ruby string (do not know how to handle): ruby-1.9.3,engine:jruby,engine_version:1.7.12.

Do you know how to tell rvm to select the jruby version? Is it possible within the Gemfile?

as suggested by the comment already linking to RVM reports Gemfile ruby as not installed

RVM's support for resolving a Ruby "engine" from the Gemfile is limited and does not match how Heroku is using (parsing) the directive.

if you really want to have it both in the Gemfile use a comment for RVM e.g.

source "https://rubygems.org"
#ruby=jruby-1.7.12
if ENV["JRUBY"] || RUBY_PLATFORM == "java"
  ruby "1.9.3", engine: "jruby", engine_version: "1.7.12"
end

gem "rails", "~> 4.1.1"
# ...
