Hi Christian,
Looks like we just crossposted.
FWIW, there is another report here:
https://hibernate.atlassian.net/browse/HHH-12347 . We should check this
case is covered too.
I marked the 2 other issues as duplicate of
https://hibernate.atlassian.net/browse/HHH-12332 , feel free to close them
as Duplicate once you have checked they are covered by your fix.
Thanks.
