Using multiple FORK channels with JGroupsTransport never acccepts the view, results in NPE ------------------------------------------------------------------------------------------ Key: ISPN-5483 URL: https://issues.jboss.org/browse/ISPN-5483 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 7.2.1.Final Reporter: Radoslav Husar Assignee: Radoslav Husar Fix For: 7.2.2.Final, 8.0.0.Alpha1 The problem is org.infinispan.remoting.transport.jgroups.JGroupsTransport#viewAccepted is never called, because org.infinispan.remoting.transport.jgroups.JGroupsTransport#startJGroupsChannelIfNeeded doesn't call viewAccepted if the connectChannel was requested. But multiple FORK channels are only going to be starting this once for the first one and the view will never be accepted. ----- Might be hiding another issue? (i.e. why transport didnt get viewAccepted() called) {noformat} 14:54:05,490 INFO [org.infinispan.factories.GlobalComponentRegistry] (ServerService Thread Pool -- 61) ISPN000128: Infinispan version: Infinispan 'Hoptimus Prime' 7.2.1.Final 14:54:05,489 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 59) MSC000001: Failed to start service jboss.infinispan.ejb.dist: org.jboss.msc.service.StartException in service jboss.infinispan.ejb.dist: org.infinispan.manager.EmbeddedCacheManagerStartupException: org.infinispan.commons.CacheException: Unable to invoke method public void org.infinispan.topology.ClusterTopologyManagerImpl.start() on object of type ClusterTopologyManagerImpl at org.wildfly.clustering.service.AsynchronousServiceBuilder$1.run(AsynchronousServiceBuilder.java:107) [wildfly-clustering-service-10.0.0.Alpha2-SNAPSHOT.jar:10.0.0.Alpha2-SNAPSHOT] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [rt.jar:1.8.0_31] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [rt.jar:1.8.0_31] at java.lang.Thread.run(Thread.java:745) [rt.jar:1.8.0_31] at org.jboss.threads.JBossThread.run(JBossThread.java:320) [jboss-threads-2.2.0.Final.jar:2.2.0.Final] Caused by: org.infinispan.manager.EmbeddedCacheManagerStartupException: org.infinispan.commons.CacheException: Unable to invoke method public void org.infinispan.topology.ClusterTopologyManagerImpl.start() on object of type ClusterTopologyManagerImpl at org.infinispan.factories.GlobalComponentRegistry.start(GlobalComponentRegistry.java:248) at org.infinispan.manager.DefaultCacheManager.wireAndStartCache(DefaultCacheManager.java:588) at org.infinispan.manager.DefaultCacheManager.createCache(DefaultCacheManager.java:554) at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:424) at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:438) at org.jboss.as.clustering.infinispan.DefaultCacheContainer.getCache(DefaultCacheContainer.java:118) at org.jboss.as.clustering.infinispan.DefaultCacheContainer.getCache(DefaultCacheContainer.java:109) at org.wildfly.clustering.infinispan.spi.service.CacheBuilder.start(CacheBuilder.java:79) at org.wildfly.clustering.service.AsynchronousServiceBuilder$1.run(AsynchronousServiceBuilder.java:102) [wildfly-clustering-service-10.0.0.Alpha2-SNAPSHOT.jar:10.0.0.Alpha2-SNAPSHOT] ... 4 more Caused by: org.infinispan.commons.CacheException: Unable to invoke method public void org.infinispan.topology.ClusterTopologyManagerImpl.start() on object of type ClusterTopologyManagerImpl at org.infinispan.commons.util.ReflectionUtil.invokeAccessibly(ReflectionUtil.java:171) at org.infinispan.factories.AbstractComponentRegistry$PrioritizedMethod.invoke(AbstractComponentRegistry.java:869) at org.infinispan.factories.AbstractComponentRegistry.invokeStartMethods(AbstractComponentRegistry.java:638) at org.infinispan.factories.AbstractComponentRegistry.internalStart(AbstractComponentRegistry.java:627) at org.infinispan.factories.AbstractComponentRegistry.start(AbstractComponentRegistry.java:530) at org.infinispan.factories.GlobalComponentRegistry.start(GlobalComponentRegistry.java:226) ... 12 more Caused by: java.lang.NullPointerException at org.infinispan.topology.ClusterTopologyManagerImpl.fetchRebalancingStatusFromCoordinator(ClusterTopologyManagerImpl.java:123) at org.infinispan.topology.ClusterTopologyManagerImpl.start(ClusterTopologyManagerImpl.java:118) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [rt.jar:1.8.0_31] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) [rt.jar:1.8.0_31] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.8.0_31] at java.lang.reflect.Method.invoke(Method.java:483) [rt.jar:1.8.0_31] at org.infinispan.commons.util.ReflectionUtil.invokeAccessibly(ReflectionUtil.java:168) ... 17 more {noformat} Full log here: https://gist.githubusercontent.com/rhusar/d9f2c68d9b3fa032084b/raw/8dc962...
