title: Can't refactor rename in Eclipse
body: <p>If I do a refactor rename on something, it tries to do it for a moment but then just reverts it right back to what it was named before.  No errors or any indication that something is wrong is shown.</p>
  
  <hr>
  
  <p>I just restarted Eclipse and now it's even worse.  Before, at least selecting <em>Refactor > Rename</em> would "box" the name and pretend it's letting you do a refactor.  Now, after restart, selecting <em>Refactor > Rename</em> does nothing.</p>
