title: Calendar failed to get the days names in different languages than English
body: <p>I'm trying to get the days of the week in German using the Calendar function getDisplayNames() with German locale.</p>
  
  <pre><code>Calendar now = Calendar.getInstance();
  Map&lt;String,Integer&gt; displayNames = now.getDisplayNames(Calendar.DAY_OF_WEEK, Calendar.LONG, new Locale("de_DE"));
  </code></pre>
  
  <p>Instead I get the day of week names in English: Sunday, Monday, .... etc.<br>
  Am I doing something wrong or it simply doesn't work?
  Maybe it got somthing to do with the toString() of my IDEA debugger console? I'm using the latest Intellij 12.1.2.</p>
