Description
Currently if I have following observer:
void observesApple(@Observes Pear apple)
and I try to change it within POM as follows:
void observesPearPOM(@Observes ProcessObserverMethod<Pear, FirstFruitObserver> event) {
// set observed type to Apple
event.configureObserverMethod().observedType(Apple.class);
}
I will get following exception:
java.lang.IllegalArgumentException: argument type mismatch at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.jboss.weld.injection.StaticMethodInjectionPoint.invoke(StaticMethodInjectionPoint.java:96) at org.jboss.weld.injection.StaticMethodInjectionPoint.invoke(StaticMethodInjectionPoint.java:86) at org.jboss.weld.injection.MethodInvocationStrategy$SimpleMethodInvocationStrategy.invoke(MethodInvocationStrategy.java:129) at org.jboss.weld.event.ObserverMethodImpl.sendEvent(ObserverMethodImpl.java:344) at org.jboss.weld.event.ObserverMethodImpl.sendEvent(ObserverMethodImpl.java:322) at org.jboss.weld.event.ObserverMethodImpl.notify(ObserverMethodImpl.java:300) at org.jboss.weld.bootstrap.events.builder.ObserverMethodConfiguratorImpl.lambda$read$47(ObserverMethodConfiguratorImpl.java:146) at org.jboss.weld.bootstrap.events.builder.ObserverMethodBuilderImpl$NotificationCallback.notify(ObserverMethodBuilderImpl.java:170) at org.jboss.weld.bootstrap.events.builder.ObserverMethodBuilderImpl$ImmutableObserverMethod.notify(ObserverMethodBuilderImpl.java:142) at org.jboss.weld.util.Observers.notify(Observers.java:138) at org.jboss.weld.event.ObserverNotifier.notifySyncObservers(ObserverNotifier.java:300) at org.jboss.weld.event.ObserverNotifier.notify(ObserverNotifier.java:288) at org.jboss.weld.event.ObserverNotifier.fireEvent(ObserverNotifier.java:165) at org.jboss.weld.event.ObserverNotifier.fireEvent(ObserverNotifier.java:147) at org.jboss.weld.manager.BeanManagerImpl.fireEvent(BeanManagerImpl.java:623) at org.jboss.weld.util.ForwardingBeanManager.fireEvent(ForwardingBeanManager.java:101)
This is likely expected but I think we should improve expcetion message to be more clear.
