title: eclipse ruby autocomplete missing options
body: <p>Eclipse 4.3.2 </p>
  
  <p>For ruby code, auto-complete doesn't show all the options. The pop window shows up for "f." does not have "read". 
  Hover the mouse on top of "f.read" shows  "(builtins) Dir::read()"</p>
  
  <pre><code>def print_all(f)
    puts f.read
  end
  </code></pre>
