title: Eclipse dot does not auto suggest
body: <p>I am using Eclipse 3.7.1 classic.</p>
  
  <p>When I type a class, it does not show the auto suggest. I dont know why, before it can pop up the function. </p>
  
  <p>I have not changed any configuration of the eclipse. </p>
  
  <p>For example, when I type <code>System</code>, it does not pop up the auto suggest, like <code>out.println</code>.</p>
