title: Rails application.js error on Production: Uncaught SyntaxError: Unexpected number
body: <p>I am getting this error from my line 1 of my application.js file:</p>
  
  <pre><code>Uncaught SyntaxError: Unexpected number   application-b975feabda9124d54cd2e23989649e07.js:1
  </code></pre>
  
  <p>The error is coming from a "2" in the comment section of jquery:</p>
  
  <pre><code>2
   * http://jquery.com/
   *

  </code></pre>
  
  <p>When working it looks like this:</p>
  
  <pre><code>/*!
   * jQuery JavaScript Library v1.7.2
   * http://jquery.com/
   *
   * Copyright 2011, John Resig
  </code></pre>
  
  <p>I get no errors in my Dev environment. Only after pushing to Heroku and application.js is compiled.</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I've searched all js files in assets/javascripts and couldn't find a 2 relating to the problem. I suspect it is related to the jquery-rails gem because when I downgraded (as a test) the gem to 2.0.1 the 2 became a 1.</p>
  
  <p>Any and all ideas are appreciated! </p>
