[jboss-jira] [JBoss JIRA] (WFLY-9246) discovery-group does not work for pooled-connection-factory because of NPE

discovery-group does not work for pooled-connection-factory because of NPE -------------------------------------------------------------------------- Key: WFLY-9246 URL: https://issues.jboss.org/browse/WFLY-9246 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 11.0.0.Beta1 Reporter: ehsavoie Hugonnet Assignee: Paul Ferraro Priority: Blocker This issue was hit during pre-testing of fixes for EAP 7.1.0.ER3. After the discussion with [~kabirkhan] and [~bstansberry] it was decided to create new Jira for the issue. *Test scenario:* * There are 4 EAP servers. * Servers 1, 3 are in cluster. They hold messages and they will be referenced in this text as JMS servers. * Servers 2, 4 are not in cluster. They have RA configured to connect to servers 1 and 3 using discovery-group, which uses JGroups. They have MDBs which resend messages from InQueue to OutQueue. Servers 2, 4 will be referenced in this text as MDB servers. *Expectation:* MDBs on MDB servers are able to discover and conenct to JMS servers. *Reality:* During activation of resource adapter on MDB servers, NPE is thrown. *Customer impact:* Resource adapter cannot be configured to dynamically discover JMS servers. This is *regression* against *7.0.z*. This issue wasn't hit before, because with EAP 7.1.0.ER3 the server did not start with this configuration. See JBEAP-12526 for details. *Detail description of issue* The following NPE arises when MDBs on MDB servers tries to connect to JMS servers via pooled-connection-factory configured to use JGroups for discovery. {code} org.apache.activemq.artemis.ra.inflow.ActiveMQActivationSpec(ra=org.apache.activemq.artemis.ra.ActiveMQResourceAdapter@e77d2b4c destination=jms/queue/InQueue destinationType=javax.jms.Queue ack=Auto-acknowledge durable=false clientID=null user=null maxSession=15): ActiveMQInternalErrorException[errorType=INTERNAL_ERROR message=AMQ119004: Failed to initialise session factory] at org.apache.activemq.artemis.core.client.impl.ServerLocatorImpl.initialise(ServerLocatorImpl.java:308) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.core.client.impl.ServerLocatorImpl.createSessionFactory(ServerLocatorImpl.java:741) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.ra.inflow.ActiveMQActivation.setup(ActiveMQActivation.java:311) [artemis-ra-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.ra.inflow.ActiveMQActivation.reconnect(ActiveMQActivation.java:658) [artemis-ra-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.ra.inflow.ActiveMQActivation$SetupActivation.run(ActiveMQActivation.java:698) [artemis-ra-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.jboss.jca.core.workmanager.WorkWrapper.runWork(WorkWrapper.java:445) at org.jboss.as.connector.services.workmanager.WildflyWorkWrapper.runWork(WildflyWorkWrapper.java:68) at org.jboss.jca.core.workmanager.WorkWrapper.run(WorkWrapper.java:223) at org.jboss.threads.SimpleDirectExecutor.execute(SimpleDirectExecutor.java:33) at org.jboss.threads.QueueExecutor.runTask(QueueExecutor.java:808) at org.jboss.threads.QueueExecutor.access$100(QueueExecutor.java:45) at org.jboss.threads.QueueExecutor$Worker.run(QueueExecutor.java:828) at java.lang.Thread.run(Thread.java:748) [rt.jar:1.8.0_131] at org.jboss.threads.JBossThread.run(JBossThread.java:320) Caused by: java.lang.NullPointerException at org.apache.activemq.artemis.api.core.jgroups.JChannelWrapper.<init>(JChannelWrapper.java:50) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.api.core.jgroups.JChannelManager.getJChannel(JChannelManager.java:74) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.api.core.JGroupsBroadcastEndpoint.initChannel(JGroupsBroadcastEndpoint.java:108) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.api.core.ChannelBroadcastEndpointFactory.createBroadcastEndpoint(ChannelBroadcastEndpointFactory.java:72) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.core.cluster.DiscoveryGroup.<init>(DiscoveryGroup.java:95) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.core.client.impl.ServerLocatorImpl.createDiscoveryGroup(ServerLocatorImpl.java:315) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] at org.apache.activemq.artemis.core.client.impl.ServerLocatorImpl.initialise(ServerLocatorImpl.java:300) [artemis-core-client-1.5.5.006-redhat-1.jar:1.5.5.006-redhat-1] ... 13 more {code}
