      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);

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-20245 [GSS](7.3.z) Cannot cast java.util.TreeMap to java.util.Date , if Collections.emptySortedMap(); and Date field name sorts after Map

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
