Infinispan's JGroupsTransport inappropriately sets its channel to null during stop(), even if a channel was provided to the constructor. {noformat} 10:10:34,923 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 71) MSC000001: Failed to start service jboss.infinispan.server.default: org.jboss.msc.service.StartException in service jboss.infinispan.server.default: org.infinispan.manager.EmbeddedCacheManagerStartupException: org.infinispan.commons.CacheException: Unable to invoke method public void org.infinispan.remoting.transport.jgroups.JGroupsTransport.start() on object of type ChannelTransport at org.wildfly.clustering.service.AsynchronousServiceBuilder$1.run(AsynchronousServiceBuilder.java:107) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) at org.jboss.threads.JBossThread.run(JBossThread.java:320) Caused by: org.infinispan.manager.EmbeddedCacheManagerStartupException: org.infinispan.commons.CacheException: Unable to invoke method public void org.infinispan.remoting.transport.jgroups.JGroupsTransport.start() on object of type ChannelTransport at org.infinispan.factories.GlobalComponentRegistry.start(GlobalComponentRegistry.java:248) at org.infinispan.manager.DefaultCacheManager.wireAndStartCache(DefaultCacheManager.java:618) at org.infinispan.manager.DefaultCacheManager.createCache(DefaultCacheManager.java:580) at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:445) at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:464) at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:455) at org.jboss.as.clustering.infinispan.DefaultCacheContainer.getCache(DefaultCacheContainer.java:120) at org.jboss.as.clustering.infinispan.DefaultCacheContainer.getCache(DefaultCacheContainer.java:111) at org.wildfly.clustering.infinispan.spi.service.CacheBuilder.start(CacheBuilder.java:80) at org.wildfly.clustering.service.AsynchronousServiceBuilder$1.run(AsynchronousServiceBuilder.java:102) ... 4 more Caused by: org.infinispan.commons.CacheException: Unable to invoke method public void org.infinispan.remoting.transport.jgroups.JGroupsTransport.start() on object of type ChannelTransport at org.infinispan.commons.util.ReflectionUtil.invokeAccessibly(ReflectionUtil.java:172) at org.infinispan.factories.AbstractComponentRegistry$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) ... 13 more Caused by: java.lang.NullPointerException at org.jboss.as.clustering.infinispan.ChannelTransport.initChannel(ChannelTransport.java:84) at org.infinispan.remoting.transport.jgroups.JGroupsTransport.initChannelAndRPCDispatcher(JGroupsTransport.java:350) at org.infinispan.remoting.transport.jgroups.JGroupsTransport.start(JGroupsTransport.java:188) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.infinispan.commons.util.ReflectionUtil.invokeAccessibly(ReflectionUtil.java:168) ... 18 more {noformat}
