[jboss-jira] [JBoss JIRA] Closed: (EJBTHREE-1366) Stop SFSB cache after the pool

Stop SFSB cache after the pool ------------------------------ Key: EJBTHREE-1366 URL: http://jira.jboss.com/jira/browse/EJBTHREE-1366 Project: EJB 3.0 Issue Type: Sub-task Components: cache Affects Versions: AS 5.0.0.Beta4 Reporter: Brian Stansberry Assigned To: Brian Stansberry Fix For: AS 5.0.0.CR1 One part of the parent issue is the SFSB cache is stopped before other elements of the container. This leads to undeployment problems like the following: 2008-05-15 13:42:35,711 WARN [org.jboss.kernel.plugins.dependency.StartStopLifecycleAction] (RMI TCP Connection(6)-127.0.0.1) Error during stop for jboss.j2ee:ear=clusteredsession-nested.jar,jar=clusteredsession-nested.jar,name=testDeepNestedStateful,service=EJB3 java.lang.RuntimeException: exception thrown while removing SFSB at org.jboss.ejb3.stateful.StatefulBeanContext.remove(StatefulBeanContext.java:668) at org.jboss.ejb3.stateful.ProxiedStatefulBeanContext.remove(ProxiedStatefulBeanContext.java:277) at org.jboss.ejb3.pool.AbstractPool.remove(AbstractPool.java:145) at org.jboss.ejb3.InfinitePool.destroy(InfinitePool.java:44) at org.jboss.ejb3.pool.ThreadlocalPool.destroy(ThreadlocalPool.java:71) at org.jboss.ejb3.EJBContainer.stop(EJBContainer.java:877) at org.jboss.ejb3.session.SessionContainer.stop(SessionContainer.java:229) at org.jboss.ejb3.stateful.StatefulContainer.stop(StatefulContainer.java:262) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.reflect.plugins.introspection.ReflectionUtils.invoke(ReflectionUtils.java:56) at org.jboss.reflect.plugins.introspection.ReflectMethodInfoImpl.invoke(ReflectMethodInfoImpl.java:110) at org.jboss.joinpoint.plugins.BasicMethodJoinPoint.dispatch(BasicMethodJoinPoint.java:66) at org.jboss.kernel.plugins.dependency.KernelControllerContextAction$JoinpointDispatchWrapper.execute(KernelControllerContextAction.java:240) at org.jboss.kernel.plugins.dependency.ExecutionWrapper.execute(ExecutionWrapper.java:45) at org.jboss.kernel.plugins.dependency.KernelControllerContextAction.dispatchExecutionWrapper(KernelControllerContextAction.java:108) at org.jboss.kernel.plugins.dependency.KernelControllerContextAction.dispatchJoinPoint(KernelControllerContextAction.java:69) at org.jboss.kernel.plugins.dependency.LifecycleAction.uninstallActionInternal(LifecycleAction.java:249) at org.jboss.kernel.plugins.dependency.InstallsAwareAction.uninstallAction(InstallsAwareAction.java:157) at org.jboss.kernel.plugins.dependency.InstallsAwareAction.uninstallAction(InstallsAwareAction.java:42) at org.jboss.dependency.plugins.action.SimpleControllerContextAction.simpleUninstallAction(SimpleControllerContextAction.java:79) at org.jboss.dependency.plugins.action.AccessControllerContextAction.uninstall(AccessControllerContextAction.java:131) at org.jboss.dependency.plugins.AbstractControllerContextActions.uninstall(AbstractControllerContextActions.java:58) at org.jboss.dependency.plugins.AbstractControllerContext.uninstall(AbstractControllerContext.java:354) at org.jboss.dependency.plugins.AbstractController.uninstall(AbstractController.java:1408) at org.jboss.dependency.plugins.AbstractController.uninstallContext(AbstractController.java:1066) at org.jboss.dependency.plugins.AbstractController.uninstallContext(AbstractController.java:988) at org.jboss.dependency.plugins.AbstractController.uninstall(AbstractController.java:515) at org.jboss.dependency.plugins.AbstractController.uninstall(AbstractController.java:471) at org.jboss.deployers.vfs.deployer.kernel.BeanMetaDataDeployer.undeploy(BeanMetaDataDeployer.java:99) at org.jboss.deployers.vfs.deployer.kernel.BeanMetaDataDeployer.undeploy(BeanMetaDataDeployer.java:46) at org.jboss.deployers.spi.deployer.helpers.AbstractSimpleRealDeployer.internalUndeploy(AbstractSimpleRealDeployer.java:69) at org.jboss.deployers.spi.deployer.helpers.AbstractRealDeployer.undeploy(AbstractRealDeployer.java:112) at org.jboss.deployers.plugins.deployers.DeployerWrapper.undeploy(DeployerWrapper.java:197) at org.jboss.deployers.plugins.deployers.DeployersImpl.doUninstallParentLast(DeployersImpl.java:1189) at org.jboss.deployers.plugins.deployers.DeployersImpl.doUninstallParentLast(DeployersImpl.java:1182) at org.jboss.deployers.plugins.deployers.DeployersImpl.uninstall(DeployersImpl.java:1144) at org.jboss.dependency.plugins.AbstractControllerContext.uninstall(AbstractControllerContext.java:354) at org.jboss.dependency.plugins.AbstractController.uninstall(AbstractController.java:1408) at org.jboss.dependency.plugins.AbstractController.uninstallContext(AbstractController.java:1066) at org.jboss.dependency.plugins.AbstractController.change(AbstractController.java:679) at org.jboss.dependency.plugins.AbstractController.change(AbstractController.java:456) at org.jboss.deployers.plugins.deployers.DeployersImpl.process(DeployersImpl.java:510) at org.jboss.deployers.plugins.main.MainDeployerImpl.process(MainDeployerImpl.java:541) at org.jboss.deployment.MainDeployer.undeploy(MainDeployer.java:638) .....

Note that fixing this doesn't completely fix the parent issue; still need to prevent shutdown of the container while still handling requests and ensure that requests that come in while shutdown is happening get an exception that triggers failover in a clustered proxy.
