title: Eclipse not giving me variable name suggestions
body: <p>well I've seen in Tips &amp; Tricks of Eclipse that it's possible to get a variable name generated by eclipse by clicking Ctrl + Space. However I'm getting empty suggestions. Fors instance I'm typing this and click ctrl + space:</p>
  
  <blockquote>
    <p>private Color </p>
  </blockquote>
  
  <p>And I am supposed to get some name suggestions on it? All I'm getting is an empty list of suggestions. So what's turned off? Any idea?</p>
  
  <p>Thanks in advance.</p>
  
  <p>This is what I want to achieve:
