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

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 Fix For: 7.1.0.Final 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 {noformat} java.lang.NullPointerException java.util.HashMap.getEntry(HashMap.java:345)
