             Summary: Distributable session may not exist after redirect to same node with optimistic locking.
                 Key: WFLY-6489
                 URL: https://issues.jboss.org/browse/WFLY-6489
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
    Affects Versions: 10.0.0.Final, 8.2.1.Final, 10.1.0.Final
            Reporter: Gabriel Lavoie
            Assignee: Paul Ferraro
            Priority: Critical
         Attachments: wildfly-10-session-issue.zip

I'm currently working on porting an application running on EAP 6.1 to WildFly 10 and am encountering multiple session/authentication issues with clustering enabled. Our login flow currently starts from a servlet that accepts the credentials, creates the session, then redirect to the welcome page. 

The first time we execute this flow after the startup of a node, the welcome page can't see at all the session created previously.
- request.getSession() creates yet another session and a new session cookie is returned.
- request.getSession(false) returns "null"

On the second attempt, the flow works as expected.

The issue can be reproduced on both a single node or a two nodes cluster, as long as <distributable /> is enabled in web.xml. 

We are currently using the master build https://ci.jboss.org/hudson/job/WildFly-latest-master/2244/, but the problem has been noticed on 10.0.0-Final and also 8.2.1-Final.

I attached a sample web application that I used to reproduce the issue. Our standalone.xml is also included with the clustering configuration we've been using for the web/session cache.
