title: Rails app on JRuby 1.7 in Nailgun mode does not start
body: <p>I installed JRuby 1.7.2 in RVM, created a gemset, executed bundle install. Now, I run this:</p>
  
  <p>Term 1:</p>
  
  <pre><code>[lzap@lzapx my_app]$ bundle exec jruby --ng-serv
  NGServer started on all interfaces, port 2113.
  </code></pre>
  
  <p>Term 2:</p>
  
  <pre><code>[lzap@lzapx my_app]$ JRUBY_OPTS="--1.9 --ng" bundle exec rails s
  </code></pre>
  
  <p>The issue is nothing happens, on both sides the terminals do not print anything, it just hangs forever. Top does not show any java/jruby processes working.</p>
  
  <p>If I try to start the application without --ng, it works okay. What is the issue? Bundler?</p>
  
  <p>Firewall is disabled of course.</p>
