[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2352) ClassCastException in Session.get()

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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
