Message not moving to default exception queue when max retries reached

Question

Hi
I've set up an advanced queue with max retrie of 5 but when the dequing fails the retry count increments but it never goes to the exception queue. The retry count stays at 6, msg_state = READY, deq_txn_id = RETRY_EXCEEDED. Any ideas?
-- drop queue if it exists
exec dbms_aqadm.stop_queue (queue_name => 'AQ$_JY_METER_ENABLE_QTAB_E');
exec dbms_aqadm.stop_queue (queue_name => 'JY_METER_ENABLE_QUE');
exec dbms_aqadm.drop_queue (queue_name  => 'JY_METER_ENABLE_QUE') ;
exec dbms_aqadm.drop_queue_table( queue_table => 'JY_METER_ENABLE_QTAB');
-- create the payload for the messages
CREATE TYPE jy_meter_enablement_typ AS OBJECT
request_id                VARCHAR2(30) ,
request_system_code       VARCHAR2(20) ,
business_process_ref      VARCHAR2(20) ,
request_type_ref          VARCHAR2(20) ,
meter_serial_number       VARCHAR2(10) ,
message_request_content   CLOB
-- Create queue table.
-- This one has a sort list so items will be enqueued first based on priority and then based on enq_time
BEGIN
   dbms_aqadm.create_queue_table (queue_table        => 'JY_METER_ENABLE_QTAB',
                                  queue_payload_type => 'JY_METER_ENABLEMENT_TYP',
                                  multiple_consumers => TRUE ,
                                  sort_list          => 'priority,enq_time' ,
                                  comment            => 'Queue table to handle JY Meter Enablement messages');
END;
-- Create Queue based on table
BEGIN
  -- retention time set 3600 seconds (ie 1 hour) so the message is kept on the queue for 1 hour after it has been dequeued.
   dbms_aqadm.create_queue (queue_name     => 'JY_METER_ENABLE_QUE',
                            queue_table    => 'JY_METER_ENABLE_QTAB' ,
                            max_retries    => 5 ,
                            retry_delay    => 2 ,
                            retention_time => 3600 ,
                            comment     => 'Queue to handle JY Meter Enablement messages in priority/enq_time order');
END;
-- start the queue
BEGIN
dbms_aqadm.start_queue (queue_name => 'JY_METER_ENABLE_QUE');
END ;
-- Add and register a subscriber to the queue to run the Dequeue procedure
BEGIN
   dbms_aqadm.add_subscriber (queue_name => 'EMO_METER_MGMT.JY_METER_ENABLE_QUE',
                              subscriber => SYS.AQ$_AGENT('JY_METER_ENABLE_QUE_SUBSCRIBER',
                                                          NULL,
                                                          NULL )
    dbms_aq.register (SYS.AQ$_REG_INFO_LIST(SYS.AQ$_REG_INFO('JY_METER_ENABLE_QUE:JY_METER_ENABLE_QUE_SUBSCRIBER',
                                                             DBMS_AQ.NAMESPACE_AQ,
                                                             'plsql://EMO_METER_MGMT.DEQUEUE.dequeue_jy_request',
                                                             HEXTORAW('FF'))),1);
END;
-- start the default exception queue
BEGIN
dbms_aqadm.start_queue(queue_name => 'EMO_METER_MGMT.AQ$_JY_METER_ENABLE_QTAB_E',
                        enqueue => FALSE,
                        dequeue => TRUE);
END ;
