title: Assetic dump for prod mode doesn't work
body: <p>I am using assetic for my assets management (see <a href="http://symfony.com/doc/current/cookbook/assetic/asset_management.html" rel="nofollow">Symfony cookbook</a>). My colleague which I am developing together runs this command to dump the assets</p>
  
  <pre><code>php app/console assetic:dump --env=prod --no-debug
  </code></pre>
  
  <p>which works fine. But when I run this command I get this output</p>
  
  <pre><code>$ php app/console assetic:dump --env=prod --no-debug
  Dumping all prod assets.
  Debug mode is off.
  
  14:35:51 [file+] C:/path/to/myapp/app/../web/js/c49cee5.js
  
  &lt;compressed file contents ...&gt;
  </code></pre>
  
  <p>followed by all the compressed JavaScript code. I mean this is displayed on my screen instead of dumping it into a file. This does not happen at my colleagues machine.</p>
  
  <p>Note:</p>
  
  <ul>
  <li>My colleague is running Max OSX, I am running Windows 7.</li>
  <li>There is no problem with not finding Java.</li>
  <li>Assets are dumped, when running command for dev environment.</li>
  </ul>
