[JBoss JIRA] (AS7-2563) NPE accessing replicated HTTP session with JSF state

Wednesday, 9 November 2011

NPE accessing replicated HTTP session with JSF state
----------------------------------------------------

                 Key: AS7-2563
                 URL: https://issues.jboss.org/browse/AS7-2563
             Project: Application Server 7
          Issue Type: Bug
          Components: Clustering
         Environment: jboss-as-7.1.0.Alpha2-SNAPSHOT (2011-11-09)
            Reporter: Marek Schmidt
            Assignee: Paul Ferraro
            Priority: Critical
         Attachments: jboss-as-numberguess-nocdi.war

1.) Start two standalone AS7 instances (standalone-ha configuration)  on node1 and node2
(e.g. <loopback-address value="127.0.1.1"/> and <loopback-address
value="127.0.2.1"/>

    node1/bin/standalone.sh --server-config=standalone-ha.xml -Djboss.node.name=node1
    node2/bin/standalone.sh --server-config=standalone-ha.xml -Djboss.node.name=node2

2.) Deploy the attached application to both instances
3.) Open http://node2:8080/jboss-as-numberguess-nocdi and enter a guess
4.) Copy the node2 JSESSIONID cookie to node1 JSESSIONID cookie
5.) Open http://node1:8080/jboss-as-numberguess-nocdi/home.jsf

Expected: Game state replicated including the latest guess.
Actual: an HTTP 500 page with the following exception appears:
The same WAR works correctly on AS6 in the same scenario.
Note that the WAR does not contain beans.xml nor use CDI in any way, in contrast to
AS7-2496

Sometimes, but not always, the following appears in the log in addition to the exception:
