The ConversationRegistry use java.lang.Object as the key to register states. We currently use it to store String http session ids. But previous (and deprecated) behaviour was to store user ids i the registry. The contract is weakly type and may be source of errors. To avoid this I suggest the following design : In ConversationRegistry deprecate public void register(Object key, ConversationState state) And add instead public void register(StateKey key, ConversationState state) public interface StateKey... public final class HttpSessionStateKey { public SessionStateKey(HttpSession session) {} }
