But we have problem during our "logout" action where we are invalidating the sessions. While a long-running conversation is started and we are invalidating the session, we are getting exceptions and the WildFly server is completly blocked. We need to restart it. Exception is always thrown with WildFly version 8.1 and 9.0alpha1. Also the hudson build #1439 ip to #1449 are not working. But using the HudsonBuild #1334, everything is working as expected. We have already posted in the forums, but didn't yet got an anwer: https://developer.jboss.org/thread/249822 The forum post has a link to a demo war where we can reproduce the problem.
