Add injection point information to exception message when injection into observer fails --------------------------------------------------------------------------------------- Key: WELD-870 URL: https://issues.jboss.org/browse/WELD-870 Project: Weld Issue Type: Enhancement Components: Events Affects Versions: 1.1.0.Final Reporter: Dan Allen Assignee: Ales Justin Fix For: 1.1.1.Final Injections that fail when an observer method is invoked are massively hard to track down. Here's the information you get: org.jboss.weld.exceptions.IllegalArgumentException: WELD-001324 Argument bean must not be null at org.jboss.weld.manager.BeanManagerImpl.getReference(BeanManagerImpl.java:714) at org.jboss.seam.exception.control.HandlerMethodImpl.notify(HandlerMethodImpl.java:187) at org.jboss.seam.exception.control.ExceptionHandlerDispatch.executeHandlers(ExceptionHandlerDispatch.java:128) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.jboss.weld.util.reflection.SecureReflections$13.work(SecureReflections.java:305) at org.jboss.weld.util.reflection.SecureReflectionAccess.run(SecureReflectionAccess.java:54) at org.jboss.weld.util.reflection.SecureReflectionAccess.runAsInvocation(SecureReflectionAccess.java:163) at org.jboss.weld.util.reflection.SecureReflections.invoke(SecureReflections.java:299) at org.jboss.weld.introspector.jlr.WeldMethodImpl.invokeOnInstance(WeldMethodImpl.java:188) at org.jboss.weld.introspector.ForwardingWeldMethod.invokeOnInstance(ForwardingWeldMethod.java:59) at org.jboss.weld.injection.MethodInjectionPoint.invokeOnInstanceWithSpecialValue(MethodInjectionPoint.java:198) at org.jboss.weld.event.ObserverMethodImpl.sendEvent(ObserverMethodImpl.java:270) at org.jboss.weld.event.ObserverMethodImpl.sendEvent(ObserverMethodImpl.java:253) at org.jboss.weld.event.ObserverMethodImpl.notify(ObserverMethodImpl.java:222) at org.jboss.weld.manager.BeanManagerImpl.notifyObservers(BeanManagerImpl.java:632) at org.jboss.weld.manager.BeanManagerImpl.fireEvent(BeanManagerImpl.java:619) at org.jboss.weld.manager.BeanManagerImpl.fireEvent(BeanManagerImpl.java:613) I expect to see the type and qualifiers at the failing injection point.
