Hello Nilo,
the magic trick is to know the right Oracle PMs :-)
In your case it would be Nigel Bayliss ( https://twitter.com/vldbb ;).

Hello,
We have found what we believe is a bug in the optimizer, and we are trying to
report this problem to Oracle with no success at all. We have found two
workarounds that generate a very good plan. The problem is with one query
executed by the EM 13c (related to tablespace monitoring). These are SYS
related objects, so it is not possible to get all the info with dbms_sqldiag
(testcase), even though support told us precisely to do that :(
So my question is, for those of you have succeeded in reporting these issues
to Oracle.. What is the magic trick ? We are hitting a wall here and it is
extremely frustrating, looks like they do not want at all to open a bug
report. And yes, we have escalated the SR with no positive result either.
Best regards.
