Yes, the above code does not work (I wrote it down without
trying it 
out), the (hopefully) correct version would be

PropertyValue[] oDateiMenuSettings;
try {
   oDateiMenuSettings = (PropertyValue[])
     com.sun.star.uno.AnyConverter.toObject(
       PropertyValue[].class,
oMenuBarSettings.getByIndex(0));
} catch (com.sun.star.lang.IllegalArgumentException e) {
   throw new RuntimeException(e.toString());
}
