      Change Collections.emptySortedMap() to new TreeMap<String,String>();

      Change from :

  private SortedMap<String, String> map = Collections.emptySortedMap();
  private Date mop; 

to:

  private SortedMap<String, String> map = new TreeMap<String,String>();
  private Date mop;

       

      Or use MarshallingConfiguration version 3

            final MarshallerFactory marshallerFactory = Marshalling.getProvidedMarshallerFactory("river");
 
        // Create a configuration
        final MarshallingConfiguration configuration = new MarshallingConfiguration();
        // Use version 3
        configuration.setVersion(3);
