Hi, I am posting this question as I cannot find any other data or information regarding this error. We are using JBoss Beta4 and sometimes when we attempt to start up our JBoss client, we are presented with the following error 2009-01-13 16:47:52,829 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Configured: name=EJB3EntityEvictionConfig state=Instantiated | java.lang.UnsupportedOperationException | at java.util.AbstractList.add(AbstractList.java:151) | at java.util.AbstractList.add(AbstractList.java:89) | at org.jboss.beans.metadata.plugins.AbstractCollectionMetaData.getValue(AbstractCollectionMetaData.java:115) | at org.jboss.kernel.plugins.dependency.PropertyDispatchWrapper.execute(PropertyDispatchWrapper.java:82) | 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.ConfigureAction.dispatchSetProperty(ConfigureAction.java:108) | at org.jboss.kernel.plugins.dependency.ConfigureAction.setAttributes(ConfigureAction.java:88) | at org.jboss.kernel.plugins.dependency.ConfigureAction.installActionInternal(ConfigureAction.java:45) | at org.jboss.kernel.plugins.dependency.KernelControllerContextAction.installAction(KernelControllerContextAction.java:135) | at org.jboss.kernel.plugins.dependency.KernelControllerContextAction.installAction(KernelControllerContextAction.java:46) | 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.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.install(AbstractController.java:574) | at org.jboss.dependency.plugins.AbstractController.install(AbstractController.java:398) | at org.jboss.deployers.vfs.deployer.kernel.BeanMetaDataDeployer.deploy(BeanMetaDataDeployer.java:69) | at org.jboss.system.deployers.TempBeanMetaDataDeployer.deploy(TempBeanMetaDataDeployer.java:48) | at org.jboss.system.deployers.TempBeanMetaDataDeployer.deploy(TempBeanMetaDataDeployer.java:35) | at org.jboss.deployers.spi.deployer.helpers.AbstractSimpleRealDeployer.internalDeploy(AbstractSimpleRealDeployer.java:65) | at org.jboss.deployers.spi.deployer.helpers.AbstractRealDeployer.deploy(AbstractRealDeployer.java:50) | at org.jboss.deployers.plugins.deployers.DeployerWrapper.deploy(DeployerWrapper.java:169) | at org.jboss.deployers.plugins.deployers.DeployersImpl.doInstallParentFirst(DeployersImpl.java:853) | at org.jboss.deployers.plugins.deployers.DeployersImpl.doInstallParentFirst(DeployersImpl.java:874) | at org.jboss.deployers.plugins.deployers.DeployersImpl.install(DeployersImpl.java:794) | at org.jboss.dependency.plugins.AbstractControllerContext.install(AbstractControllerContext.java:327) | 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.deployers.plugins.deployers.DeployersImpl.process(DeployersImpl.java:498) | at org.jboss.deployers.plugins.main.MainDeployerImpl.process(MainDeployerImpl.java:506) | at org.jboss.system.server.profileservice.ProfileServiceBootstrap.loadProfile(ProfileServiceBootstrap.java:246) | at org.jboss.system.server.profileservice.ProfileServiceBootstrap.start(ProfileServiceBootstrap.java:131) | at org.jboss.bootstrap.AbstractServerImpl.start(AbstractServerImpl.java:408) | at org.jboss.Main.boot(Main.java:208) | at org.jboss.Main$1.run(Main.java:534) | at java.lang.Thread.run(Thread.java:595) | 2009-01-13 16:47:53,751 INFO [org.jboss.invocation.unified.server.UnifiedInvokerHA] Service name is jboss:service=invoker,type=unifiedha | This happens at the very start of JBoss start-up. Originally we believed it to be because we had specified too many regions in the ejb3-entity-cache-beans.xml file...however we have now reduced this to just 5 regions. I assume that there must be something wrong with the file, however I fail to understand why sometimes JBoss accepts it fine, and other times it does not. Can anyone possibly help me discover what is causing this issue?
