@beikov something's wrong here, since the tests broke. Is there something special I need to do, or perhaps there's a bug?

So right now, caching of criteria queries depends on a session level setting QuerySettings.CRITERIA_PLAN_CACHE_ENABLED/Session#setCriteriaPlanCacheEnabled(). I wasn't sure if we wanted to cache all criteria queries by default, but assumed it might not be appropriate. Also, there is a sort of tension between caching based on HQL representation and the object identity of the criteria query if criteria tree copying is disabled.

Maybe we can discuss this a bit on Wednesday?

OK, sure 👍

Closing, since the query plan cache is still based on object identity for criteria queries.
