title: DateFormatSymbols gives the wrong translation of months/days
body: <p>We've recently migrated from Java 8 to 11. Upon testing our new version we discovered that when a date is spelled out (dddd, dd MMMM yyyy) the resulting months/days are in English. Our default locale is set to nl_NL. Reverting back to Java 8 fixes the problem so it is related to the upgrade. We've tried a number of things:</p>
  <ul>
  <li>Setting default locale tot nl_NL in docker image and application</li>
  <li>Setting &quot;java.locale.providers&quot; to &quot;COMPAT,CLDR&quot;</li>
  <li>Upgrading libraries</li>
  </ul>
  <p>When debugging our acceptatie environment, we notice that DateFormatSymbols has the wrong translation of months/weeks.</p>

  <p>EDIT:
  The problem occurs when generating Word documents from user created templates. These templates contain mergefields, these mergefields are used to create the correct document. The dateformat is being set on the mergefield (e.g.  { MERGEFIELD Merge_Date @ &quot;dddd, MMMM d, yyyy&quot; }). Library used for generating these documents is Aspose Word. The Aspose library is using the <code>DateFormatSymbols</code> for conversion.</p>
  <p>Help would be appreciated, we've ran out of idea's.</p>
