[jboss-jira] [JBoss JIRA] Closed: (JBAS-5201) EJB2 Entity with cache invalidation fails to deploy with NPE

EJB2 Entity with cache invalidation fails to deploy with NPE ------------------------------------------------------------ Key: JBAS-5201 URL: http://jira.jboss.com/jira/browse/JBAS-5201 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: EJB2 Affects Versions: JBossAS-5.0.0.Beta3 Reporter: Brian Stansberry Assigned To: Brian Stansberry Fix For: JBossAS-5.0.0.CR1 An entity with cache invalidation configured will fail to deploy. This is the cause of the failing o.j.t.cluster.multicfg.ejb2.test.CacheInvalidationUnitTestCase. Example bean config: <entity> <ejb-name>cif_CachedEntityPK</ejb-name> <configuration-name>Standard CMP 2.x EntityBean with cache invalidation</configuration-name> <cache-invalidation>true</cache-invalidation> </entity> Failure: 2008-02-01 23:32:04,875 DEBUG [org.jboss.ejb.plugins.AbstractInstanceCache] Starting InvalidableEntityInstanceCache... 2008-02-01 23:32:04,878 DEBUG [org.jboss.ejb.EntityContainer] Starting failed jboss.j2ee:jndiName=local/cif_CachedEntityPK@8115601,service=EJB java.lang.NullPointerException at org.jboss.ejb.plugins.InvalidableEntityInstanceCache.start(InvalidableEntityInstanceCache.java:123) at org.jboss.ejb.EntityContainer.startService(EntityContainer.java:352) at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:299) at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:245) at sun.reflect.GeneratedMethodAccessor4.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:157) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:96) at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:668) at org.jboss.system.microcontainer.ServiceProxy.invoke(ServiceProxy.java:167) at $Proxy5.start(Unknown Source) at org.jboss.system.microcontainer.StartStopLifecycleAction.installAction(StartStopLifecycleAction.java:42) at org.jboss.system.microcontainer.StartStopLifecycleAction.installAction(StartStopLifecycleAction.java:37) at org.jboss.dependency.plugins.action.SimpleControllerContextAction.simpleInstallAction(SimpleControllerContextAction.java:62) at org.jboss.dependency.plugins.action.AccessControllerContextAction.install(AccessControllerContextAction.java:71) at org.jboss.dependency.plugins.AbstractControllerContextActions.install(AbstractControllerContextActions.java:51) at org.jboss.dependency.plugins.AbstractControllerContext.install(AbstractControllerContext.java:327) at org.jboss.system.microcontainer.ServiceControllerContext.install(ServiceControllerContext.java:255) at org.jboss.dependency.plugins.AbstractController.install(AbstractController.java:1309) at org.jboss.dependency.plugins.AbstractController.incrementState(AbstractController.java:734) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:862) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:784) at org.jboss.dependency.plugins.AbstractController.change(AbstractController.java:622) at org.jboss.dependency.plugins.AbstractController.change(AbstractController.java:411) at org.jboss.system.ServiceController.doChange(ServiceController.java:659) at org.jboss.system.ServiceController.start(ServiceController.java:431) ..... Problem is JBossEntityMetaData.getCacheInvalidationConfig() can return null if jobss.xml doesn't include a cache-invalidation-config element; in 4.x it wouldn't because a default value would be set. Likely solution is either 1) to add a JBossEntityMetaData.determineCacheInvalidationConfig() method or 2) just lazy create a default config in JBossEntityMetaData.getCacheInvalidationConfig(). The latter is a simpler solution; the former is used elsewhere when there is a need to merge metadata from a <container-configuration/>, but there is no cache invalidation configuration in <container-configuration/>. Either way, this will require a new jboss-metadata release.
