12cR2 DBMS_SCHEDULER Resource_Queues Not Working (Doc ID 2272234.1)

Symptoms

On : 12.2.0.1 version, RDBMS

Created a Resource Queue with 1 Resource with enforce_constraints.



The Expectation is that session A and B can't run simultaneously there is only 1 unit in the resource and all jobs need 1 resource to run.
But they all run almost parallel (with the delay of the time required to start the job in different window.)
Also while monitoring the view, it always shows Units_used=0 and job_running_count=0, even after executing the job multiple times in a row.
