Hi Folks, I work in the IBM CDI implementation team. We are running the CDI 2.0 TCK/CDS and get a test failure on: org.jboss.cdi.tck.tests.extensions.lifecycle.broken.observerMethod. ObserverMethodWithoutNotifyMethodTest that I need some advice on. The test has: import javax.enterprise.inject.spi.DeploymentException; @ShouldThrowException(DeploymentException.class) // unable to process ObserverMethodConfigurator due to missing notify method impl @Test @SpecAssertions({ @SpecAssertion(section = AFTER_BEAN_DISCOVERY, id = "ee") }) public void unableToProcessObserverMethodConfigurator() { } This behaviour is specified in https://docs.jboss.org/cdi/spec/2.0/cdi-spec-with- assertions.html#after_bean_discovery (search for "ee)" ) ee) If the container is unable to process the ObserverMethodConfigurator it automatically detects the problem and treats it as a deployment problem. ObserverMethodWithoutNotifyMethodTest.unableToProcessObserverMethodC onfigurator() However what we see coming back from Weld is not a javax DeploymentException but a javax DefinitionException wrapping a weld DeploymentException cause Stack Dump = javax.enterprise.inject.spi.DefinitionException: org.jboss.weld.exceptions.DeploymentException: WELD-000179: ObserverMethodConfigurator created by org.jboss.cdi.tck.tests. extensions.lifecycle.broken.observerMethod.AfterBeanDiscoveryObserver@d31423c cannot be processed at org.jboss.weld.bootstrap.events.AfterBeanDiscoveryImpl. finish(AfterBeanDiscoveryImpl.java:180) <<<<<<< Problem???? at org.jboss.weld.bootstrap.events.AfterBeanDiscoveryImpl. fire(AfterBeanDiscoveryImpl.java:76) at org.jboss.weld.bootstrap.WeldStartup.deployBeans(WeldStartup.java:446) at org.jboss.weld.bootstrap.WeldBootstrap.deployBeans(WeldBootstrap.java:83) at com.ibm.ws.cdi.impl.CDIContainerImpl.startInitialization(CDIContainerImpl.java:149) at com.ibm.ws.cdi.liberty.CDIRuntimeImpl.applicationStarting(CDIRuntimeImpl.java:400) at com.ibm.ws.container.service.state.internal.

So the bottom line is the CDI CTS/TCK test org.jboss.cdi.tck.tests.extensions.lifecycle.broken.observerMethod. ObserverMethodWithoutNotifyMethodTest fails due to the inconsistency. Have I missunderstood the spec contradiction or missed some part of Weld integration needed? Gordon.
