@Kishore Pothireddy Sorry, but I do not know that any more than you. I am just an ordinary Hibernate user that is from time to time fixing bug or two.

Thanks for the update @Čedomir Igaly . Any ETA on fix availability in 6.6?

Cause of the problem is same as in https://hibernate.atlassian.net/browse/HHH-18069, patch that fixed it should be backported to 6.6 branch - PR #9685
