( https://hibernate.atlassian.net/browse/HHH-14135?atlOrigin=eyJpIjoiMzI1Nz... ) Hi David Vamvakas ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) , you mentioned 5.3.18 but this version has not yet been released, so not sure if you are trying to upgrade from 5.4.17 to 5.4.18 or from 5.3.17 to 5.4.18. Can you please provide a test case, this will help us to spot the issue?
