Howdy, I would mention one other possibility, unrelated to synchronization, which may cause this behavior.
If your session listener simply increments a counter on every sessionCreated() and decrements the counter on every sessionDestroyed(), it is vulnerable to this behavior. When the server is restarted, if there are active sessions they are persisted by default. Then the server comes back up, and all these sessions are active, without a session created event, so your listener has a counter value of 0, but there are actually >0 active sessions. When these are destroyed as usual, sessionDestroyed() will be called for them, decrementing your counter and resulting in a negative value.
