JBossMarshaller can be used before properly initialized ------------------------------------------------------- Key: ISPN-2553 URL: https://issues.jboss.org/browse/ISPN-2553 Project: Infinispan Issue Type: Bug Components: Marshalling Affects Versions: 5.2.0.Beta4 Reporter: Radim Vansa Assignee: Galder Zamarreño Fix For: 5.2.0.Beta6 The {{JBossMarshaller}} can be used before its {{start()}} method is called. I've noticed that with replicated cache without transactions, an OOB thread can start demarshalling {{SingleRpcCommand}} in {{CacheRpcCommandExternalizer}} but when it tries to create a new unmarshaller (through {{AbstractJBossMarshaller.startObjectInput(...)}} and the {{marshallerTL.initialValue()}} the {{baseCfg}} configuration is not fully initialized yet and this results in creating marshallers in {{PerThreadInstanceHolder}} with {{objectTable == null}}. Then, objects are deserialized to {{null}}. I have verified this by inserting some log messages into constructors and start method: {code} 19:49:02,404 INFO [org.infinispan.marshall.jboss.AbstractJBossMarshaller] (pool-1-thread-1) Creating AbstractJBossMarshaller with org.jboss.marshalling.MarshallingConfiguration@1d296aa3: classExternalizerFactor y=<org.infinispan.marshall.jboss.SerializeWithExtFactory@a18024a> exceptionListener=<null> instanceCount=16 classCount=8 bufferSize=512 version=3 19:49:02,409 INFO [org.infinispan.marshall.jboss.AbstractJBossMarshaller] (pool-1-thread-1) Creating JBossMarshaller org.infinispan.marshall.jboss.JBossMarshaller@2e3e4d73 19:49:02,410 INFO [org.infinispan.marshall.jboss.AbstractJBossMarshaller] (pool-1-thread-1) Starting JBossMarshaller {code} and into the thread-local initialization and to {{getUnmarshaller()}} just before {{factory.createUnmarshaller}}: {code} 19:49:02,410 ERROR [org.infinispan.marshall.jboss.AbstractJBossMarshaller] (OOB-49,rvansa-22965) No object table in org.jboss.marshalling.MarshallingConfiguration@7c4ed0bc: classExternalizerFactory=<org.infinisp an.marshall.jboss.SerializeWithExtFactory@a18024a> exceptionListener=<null> instanceCount=16 classCount=8 bufferSize=512 version=3, base is org.jboss.marshalling.MarshallingConfiguration@1d296aa3: classExternali zerFactory=<org.infinispan.marshall.jboss.SerializeWithExtFactory@a18024a> exceptionListener=<null> instanceCount=16 classCount=8 bufferSize=512 version=3 19:49:02,453 ERROR [org.infinispan.marshall.jboss.AbstractJBossMarshaller] (OOB-49,rvansa-22965) Unmarshaller with cfg org.jboss.marshalling.MarshallingConfiguration@7c4ed0bc: classExternalizerFactory=<org.infin ispan.marshall.jboss.SerializeWithExtFactory@a18024a> exceptionListener=<null> instanceCount=16 classCount=8 bufferSize=512 version=3 {code} See that the timestamps for {{start()}} and thread-local initialization are same, and the base configuration ({{baseCfg}}) does not have {{objectTable}} initialized.
