      Important Notes

      In EAP 7.2.5, SessionExpirationScheduler#schedule for the session key is called when starting node1 of (*A), so the session will successfully removed when it is timed out. Likewise, when starting node1 of (*B), SessionExpirationScheduler#schedule for the session key is called. In this case, the session has already been timed out, so it will immediately removed.

      At first glance, this behavior seems fine, but not in the situation with multiple sessions as the following test below.

      1. Create 10 sessions by accessing http://localhost:8080/jboss-helloworld/HelloWorld using curl_many.sh in helloworld_02534900.zip.
      2. Count the number of sessions for node1 and node2. 
        $ jmap -histo:live <pid_of_node1> | grep SessionAttributesKey
$ jmap -histo:live <pid_of_node2> | grep SessionAttributesKey
      3. Stop node1 before reaching session timeout.
      4. Start node1 before reaching session timeout. ..... (*C)
      5. Wait for session timeout.
      6. Count the number of sessions again for node1 and node2. 
        $ jmap -histo:live <pid_of_node1> | grep SessionAttributesKey
$ jmap -histo:live <pid_of_node2> | grep SessionAttributesKey

        (EAP 7.0.0) All 10 sessions will be live even after it is timed out. <--- NOT EXPECTED
        (EAP 7.2.5) Only 1 session will become dead. Remaining 9 sessions will be live even after they are timed out. <--- NOT EXPECTED

      In EAP 7.2.5, when starting node1 of (*C), SessionExpirationScheduler#schedule is called for only 1 session of 10 sessions. So, the 1 session will successfully be removed when it is timed out, but the remaining 9 sessions will not be removed.

      I think SessionExpirationScheduler#schedule should be called for all sessions.

So, the 1 session will successfully be removed when it is timed out, but the remaining 9 sessions will not be removed. I think SessionExpirationScheduler#schedule should be called for all sessions.

      In cluster environment, if we shutdown the node in which a session is created, the session continues to remain even after it is timed out. Of course, by accessing with the same session id, the session which is remaining and already timed out will become dead. However, all sessions are not necessarily accessed again after session failover. It looks memory leak especially when the number of such remaining sessions is large.

      This issue can be reproduced in EAP 7.0.0 which the user is currently using. It can also be reproduced in EAP 7.2.5 in the situation with multiple sessions.
