[hibernate-dev] Release Connection provider resources

Hey, guys, in Hibernate 3 you had ConnectionProvider#close() method which releases all the resources used by the connection provider. In hibernate 4 ConnectionProvider is a service without this method, but you have Stoppable interface with stop() method which I guess do this work. But the problem is I can't use instanceof to determine whether current connection provider is Stoppable, because internally hibernate uses proxyes. What is right way to replace old ConnectionProvider#close()? Dmitry Geraskov
