[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2352) ClassCastException in Session.get()
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2352?page=all ]
Emmanuel Bernard resolved HHH-2352:
-----------------------------------
Resolution: Rejected
We discussed that in the past , and I think we decided that this is not an API violation.
You are doing a CCE error becuase there is no Item having this id (since a client has this
id already). If you are unsure of the type, use a query
ClassCastException in Session.get()
-----------------------------------
Key: HHH-2352
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2352
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.1
Environment: Hibernate 3.2.1
Reporter: Alexey Romanchuk
Priority: Critical
We have inheritance with joined-subclass mapping. Imagine that we have parent class -
BaseObject and two subclasses - Client and Item. We enable second level cache on
BaseObject.
try to load Client in first session
Client client = ( Client ) s1.get( Client.class, 1851727l );
after this we have this client in second level cache.
Next - load another subclass with same id:
Item item = ( Item ) s2.get( Item.class, 1851727l );
and here we have ClassCastException because hibernate found BaseObject (Client) and
return it instead of null.
The solution is class check in
org.hibernate.event.def.DefaultLoadEventListener.loadFromSecondLevelCache() function. This
is crititcal bug that violates Session API.
