title: Eclipse - Annoying thread-switching while debugging a thread's execution
body: <p>I am seeing a very annoying problem with my eclipse. While debugging the execution of a particular thread, when I press <code>F6</code> (Step next), the control moves on to some other random thread.</p>

  <p>In the above screenshot, I am debugging <code>[Thread-691]</code>, when I step next, <em>sometimes</em> eclipse moves away from the selected thread!</p>
  <p>Any idea why this is happening and how to fix this?</p>
