[jboss-jira] [JBoss JIRA] Closed: (EJBTHREE-659) SFSB throws exception with second passivation

SFSB throws exception with second passivation --------------------------------------------- Key: EJBTHREE-659 URL: http://jira.jboss.com/jira/browse/EJBTHREE-659 Project: EJB 3.0 Issue Type: Bug Affects Versions: EJB 3.0 RC8 - FD Reporter: Ben Wang Assigned To: Ben Wang Fix For: EJB 3.0 RC9 - FD Original Estimate: 2 days Remaining Estimate: 2 days I have created a test case to illustrate this for both SimpleStatefulCache and StatefulTreeCache, NestedBeanUnitTestCase (cache and clusteredsession). Basically, if we do this: bean.getXXX sleep(10000); // to passivate bean.getXXX; // to acitvate sleep(10000); // to passivate again This will produce: 2006-07-24 04:46:59,358 ERROR [org.jboss.ejb3.cache.simple.SimpleStatefulCache] problem passivation thread^M javax.ejb.EJBException: Could not passivate; failed to save state^M at org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager.passivateSession(StatefulSessionFilePersistenceManager.java:363)^M at org.jboss.ejb3.cache.simple.SimpleStatefulCache.passivate(SimpleStatefulCache.java:196)^M at org.jboss.ejb3.cache.simple.SimpleStatefulCache$SessionTimeoutTask.run(SimpleStatefulCache.java:129)^M Caused by: java.lang.NullPointerException^M at org.jboss.serial.util.StringUtil.calculateUTFSize(StringUtil.java:319)^M at org.jboss.serial.util.StringUtil.saveString(StringUtil.java:63)^M at org.jboss.serial.objectmetamodel.DataContainer$DataContainerDirectOutput.writeUTF(DataContainer.java:265)^M at org.jboss.ejb3.stateful.StatefulBeanContextReference.writeExternal(StatefulBeanContextReference.java:65)^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.JBossObjectOutputStream.writeObjectOverride(JBossObjectOutputStream.java:181)^M at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:287)^M at org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager.passivateSession(StatefulSessionFilePersistenceManager.java:347)^M ... 2 more^M This is caused by a bug from ProxiedStatefuleBeanContext serialization where we dont serialiaze parentRef if it is not null.
