----------------------------------

             Summary: IllegalStateException: java.util.ConcurrentModificationException
                 Key: WFLY-11140
                 URL: https://issues.jboss.org/browse/WFLY-11140
             Project: WildFly
          Issue Type: Bug
          Components: MP Config
    Affects Versions: 14.0.1.Final, 14.0.0.Final
            Reporter: tommaso borgato
            Assignee: Jeff Mesnil


One of the many affected scenarios is [perflab_eap-7x-failover-http-session-shutdown-dist-sync-shared-sessions|https://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/perflab_eap-7x-failover-http-session-shutdown-dist-sync-shared-sessions/1/console-perf18/consoleText]: it is a 4 nodes (running with the standalone-ha.xml configuration) fail-over scenario where the deployed EAR contains two WAR sharing http sessions:

{{clusterbench-ee7-shared-sessions.ear/META-INF/jboss-all.xml}}:
{noformat}
<jboss umlns="urn:jboss:1.0">
    <shared-session-config xmlns="urn:jboss:shared-session-config:1.0">
        <session-config>
            <cookie-config>
                <path>/</path>
            </cookie-config>
        </session-config>
    </shared-session-config>
</jboss>
{noformat}

During server shut-down the EAR is stopped and we observe the following error:

Also other scenarios like [perflab_eap-7x-failover-http-session-shutdown-dist-sync-nb-state-transfer|https://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/perflab_eap-7x-failover-http-session-shutdown-dist-sync-nb-state-transfer] and [perflab_eap-7x-failover-remote-jdg-session-shutdown-invalidation-sync-hotrod|https://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/perflab_eap-7x-failover-remote-jdg-session-shutdown-invalidation-sync-hotrod] exhibits the same error: I assume it does not depend on the shared sessions configuration mentioned above;

Find attached:
- the complete server log (perf18-consoleText.txt)
- the EAR used for the shared-sessions scenario (clusterbench-ee7-shared-sessions.ear)
- the EAR used for the [perflab_eap-7x-failover-http-session-shutdown-dist-sync-nb-state-transfer|https://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/perflab_eap-7x-failover-http-session-shutdown-dist-sync-nb-state-transfer] scenario (clusterbench-ee7.ear)
