A bug found in 188.8.131.52…this occurs when AQ_TM_PROCESSES=0
At the time of this writing MOS didn’t have the information publicly available, I had to open a SR to get the resolution.
The fix is to set the database initialization parameter to a non-zero value and gather fixed object statistics again.
SQL> exec dbms_stats.gather_fixed_objects_stats;
BEGIN dbms_stats.gather_fixed_objects_stats; END;
