Differentiate between session timeout and spring concurrency-control max sessions

Question

I'm extending HttpSessionEventPublisher and i want in my sessionDestroyed() method to differentiate between sessions that were timed out and ones that closed because of concurrency-control max sessions. Is there a flag in HttpSessionEvent or the authentication object? if not can i override the session closing that the concurrency-control do?

EDIT: I added a costume concurrentSessionControlAuthenticationStrategy but I get this error: Configuration problem: session-authentication-strategy-ref attribute cannot be used in combination with

my security.xml:

<security:session-management
            session-authentication-strategy-ref="playerConcurrentSessionControlStrategy">
            <security:concurrency-control
                max-sessions="1" />
        </security:session-management>

PlayerConcurrentSessionControlStrategy :

@Component
public class PlayerConcurrentSessionControlStrategy extends ConcurrentSessionControlStrategy 

what to do?
