[hibernate-dev] ClassCastException with 2nd level cache not entirely gone?

Hi all, We just hit the ClassCastException problem with 2nd level cache reported by other people. But... we're using *4.3.4.Final* so I'm not sure this issue has really been fixed with 4.3.4.Final. Typically, we have the following hierarchy: AbstractUser TechnicalUser (id = 1) AccountManager (id = 2) entityManager.find(AccountManager.class, 1) returns the TechnicalUser 1 and not null if the 2nd level cache is enabled (and the object is in the cache). I'm pretty sure it's not the expected behavior. Should I open a JIRA issue or do you prefer to reopen an existing issue? I'm not entirely sure it's due to the same problem so I thought I might as well ask here. Thanks for your feedback. -- Guillaume
