CacheManagerTest.testCacheManagerRestartReusingConfigurations random failures ----------------------------------------------------------------------------- Key: ISPN-4512 URL: https://issues.jboss.org/browse/ISPN-4512 Project: Infinispan Issue Type: Bug Components: Core, Test Suite - Core Affects Versions: 7.0.0.Alpha4 Reporter: Dan Berindei Assignee: William Burns Priority: Blocker Labels: testsuite_stability Attachments: CacheManagerTest_t_ISPN-4154_failing_elasticity_test_20140707.log.gz When a new cache manager is started with the same configuration, it uses the JGroupsTransport instance. In some rare cases, the JGroupsTransport keeps using the old marshaller, which doesn't work, and the cache fails to start: {noformat} 23:54:08,203 TRACE (testng-CacheManagerTest:___defaultcache) [JGroupsTransport] dests=[NodeB-24139], command=CacheTopologyControlCommand{cache=___defaultcache, type=JOIN, sender=NodeA-33664, joinInfo=CacheJoinInfo{consistentHashFactory=org.infinispan.distribution.ch.impl.ReplicatedConsistentHashFactory@b8c8791, hashFunction=MurmurHash3, numSegments=60, numOwners=2, timeout=240000, totalOrder=false, distributed=false}, topologyId=0, currentCH=null, pendingCH=null, throwable=null, viewId=3}, mode=SYNCHRONOUS, timeout=240000 23:54:08,207 DEBUG (testng-CacheManagerTest:___defaultcache) [VersionAwareMarshaller] Object is not serializable java.io.NotSerializableException: org.infinispan.topology.CacheTopologyControlCommand at org.jboss.marshalling.river.RiverMarshaller.doWriteObject(RiverMarshaller.java:890) at org.jboss.marshalling.AbstractObjectOutput.writeObject(AbstractObjectOutput.java:58) at org.jboss.marshalling.AbstractMarshaller.writeObject(AbstractMarshaller.java:111) at org.infinispan.commons.marshall.jboss.AbstractJBossMarshaller.objectToObjectStream(AbstractJBossMarshaller.java:73) at org.infinispan.marshall.core.VersionAwareMarshaller.objectToBuffer(VersionAwareMarshaller.java:77) at org.infinispan.commons.marshall.AbstractMarshaller.objectToBuffer(AbstractMarshaller.java:41) at org.infinispan.commons.marshall.AbstractDelegatingMarshaller.objectToBuffer(AbstractDelegatingMarshaller.java:85) at org.infinispan.remoting.transport.jgroups.MarshallerAdapter.objectToBuffer(MarshallerAdapter.java:23) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.marshallCall(CommandAwareRpcDispatcher.java:335) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.processSingleCall(CommandAwareRpcDispatcher.java:352) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.invokeRemoteCommand(CommandAwareRpcDispatcher.java:165) at org.infinispan.remoting.transport.jgroups.JGroupsTransport.invokeRemotely(JGroupsTransport.java:526) at org.infinispan.topology.LocalTopologyManagerImpl.executeOnCoordinator(LocalTopologyManagerImpl.java:290) at org.infinispan.topology.LocalTopologyManagerImpl.join(LocalTopologyManagerImpl.java:100) at org.infinispan.statetransfer.StateTransferManagerImpl.start(StateTransferManagerImpl.java:104) {noformat} The only test that does this is CacheManagerTest.testCacheManagerRestartReusingConfigurations.
