Steve Ebersole commented on WFLY-6596:
--------------------------------------
That would indicate to me that you are using the same "cache region" for storing both Country and Member data. Are you doing that explicitly (in annotations or XML, etc)?
For illustration, when you have a {{Country#9}} and a {{Member#9}} both of those get stored into their respective cache region using a "cache key". What I think is happening is that in your case both {{Country#9}} and a {{Member#9}} get stored into the same "Map" using the key 9... they collide. So if you put {{Country#9}} into the cache and then try to find {{Member#9}} you'd get back the {{Country#9}} entry.
That would jive with a recent performance enhancement that changed the structure of this "cache key". We used to essentially use a tuple of {{rootEntityName,id}}. The recent change was performance related, and changed that to instead use just the {{id}}. But obviously we need to be correct, then performant.
If my hunch is correct you could work around this by using distinct regions for your entities.
You could also work around it by controlling the factory responsible for creating those "cache keys". Unfortunately that is a l lot of work (too much) atm.
I created [HHH-11083|https://hibernate.atlassian.net/browse/HHH-11083] to fix the bug in Hibernate.
