title: High CPU usage in Eclipse when nothing in progress
body: <p>I have this problem with eclipse Mars.2</p>
  
  <p>Build Automatically is disabled and nothing is in progress.
  Each time I start eclipse, there is a high CPU usage. Here is what JProfiler says:

  <p>Eclipse seems to be compiling something, by why?</p>
  
  <p>Another strange thing is that if I try to quit Eclipse, the process does not terminate.</p>
  
  <p>Thanks</p>
