Nested bean during repeated failover throw NPE ---------------------------------------------- Key: EJBTHREE-612 URL: http://jira.jboss.com/jira/browse/EJBTHREE-612 Project: EJB 3.0 Issue Type: Bug Components: Clustering Reporter: Ben Wang Assigned To: Ben Wang Fix For: EJB 3.0 RC9 - FD I have encountered this during writing more complete unit testing for sfsb clustering. The test case is: org.jboss.ejb3.test.clusteredsession.unit.testStatefulBeanCounterFailover Here is how to reproduce it: Create a ParentBean and NestedBean for nested sfsb case. Hit node1, failover to node2, and execute will produce the following exception: Caused by: java.lang.NullPointerException^M at org.jboss.ejb3.stateful.StatefulBeanContextReference.<init>(StatefulBeanContextReference.java:51)^M at org.jboss.ejb3.stateful.ProxiedStatefulBeanContext.writeExternal(ProxiedStatefulBeanContext.java:92)^M at org.jboss.serial.persister.ExternalizePersister.writeData(ExternalizePersister.java:58)^M at org.jboss.serial.objectmetamodel.ObjectDescriptorFactory.describeObject(ObjectDescriptorFactory.java:275)^M at org.jboss.serial.objectmetamodel.DataContainer$DataContainerDirectOutput.writeObject(DataContainer.java:197)^M at org.jboss.serial.io.JBossObjectOutputStreamSharedTree.writeObjectOverride(JBossObjectOutputStreamSharedTree.java:59)^M at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:287)^M at org.jboss.cache.marshall.EnhancedTreeCacheMarshaller.marshallObject(EnhancedTreeCacheMarshaller.java:258)^M @ Note that this error has already existed before any refactoring is in place.
