Feature: Support for JRuby
Improve startup time by disabling JIT and forcing client JVM mode. This can
be accomplished by adding
```ruby
require 'aruba/config/jruby'
```
*Note* - no conflict resolution on the JAVA/JRuby environment options is
done; only merging. For more complex settings please manually set the
environment variables in the hook or externally.
Refer to http://blog.headius.com/2010/03/jruby-startup-time-tips.html for other tips on startup time.

require 'aruba/config/jruby'
RSpec.describe 'running commands with before :command hook', :type => :aruba do
it 'sets up for efficient JRuby startup' do
with_environment 'JRUBY_OPTS' => '-d' do
run_command_and_stop('env')
expect(last_command_started.output).to include 'JRUBY_OPTS=--dev -X-C -d'
end
end
end
"""
When I run `rspec`
Then the specs should all pass
