[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2921) Polymorphic query breaks if entity proxy already exists in session

[Johan Hoogenboezem (JIRA)]

Johan Hoogenboezem commented on HHH-2921:
-----------------------------------------

This turns it into a chicken-egg problem. I need to evict the proxy, but I need to run the query to get the proxy. 
Otherwise I have to dig through the rest of the code running in the same transaction and find the place where the proxy was being placed into the session and evict it there.
Wouldn't the Hibernate code be the best place for the eviction of the entity from the session? 
I think this forces developers to know more about the internals of Hibernate than they need to.
