title: Java Web Start Applet opening new Browser Window/Tab ignoring target
body: <p>Having successfully migrated an applet to a java webstart applet, I notice that every call to </p>
  
  <pre><code>getAppletContext().showDocument(
  new URL("http://"+ host+ "/" + filename + language + ".htm"),
   "Helppage");
  </code></pre>
  
  <p>opens a new browser window (Win 7/MSIE11) or tab (firefox depending on configuration) though I obviously request a specific named possibly already open browser window. </p>
  
  <p>Has anyone successfully managed to redirect those calls to one browser window (tab)? If yes, how? </p>
  
  <p>Looks a similar context to <a href="https://stackoverflow.com/questions/35780756/how-do-i-close-a-browser-window-that-was-opened-by-java-web-start">How do I close a browser window that was opened by Java Web Start</a></p>
