title: Eclipse IDE - Open Call Hierarchy is empty/broken
body: <p>What should I do, if the "Open Call Hierarchy" is broken (empty for every method in a project)?  It only shows the name of the method I wanted to see the call hierarchy for.  This happens for all methods I try, even though they are all called by other methods.</p>
  
  <p>It is very useful for code navigation.  I do not know how to work without it!</p>
  
  <p>I've tried:</p>
  
  <ol>
  <li>Opening <code>eclipse.exe -clean -refresh</code></li>
  <li>Restarting Eclipse</li>
  <li>Closing and reopening the project</li>
  <li>Updating the project</li>
  <li>Renaming the .metadata file</li>
  </ol>
  
  <p>I've checked that it searches the whole workspace, and there are no filters on.</p>
