[weld-issues] [JBoss JIRA] Commented: (WELD-842) Event injection via constructor injection results in stacktrace.

Stuart Douglas commented on WELD-842:
-------------------------------------
HelloWorldService is not proxiable, so this is a validation error that should have been
picked up by the container
Event injection via constructor injection results in stacktrace.
-----------------------------------------------------------------
Key: WELD-842
URL: https://issues.jboss.org/browse/WELD-842
Project: Weld
Issue Type: Bug
Affects Versions: 1.1.0.Final
Reporter: Christopher Brock
{code}
/**
* @author Mike Brock .
*/
@ApplicationScoped
public class HelloWorldService {
private Event<ResponseEvent> responseEvent;
@Inject
public HelloWorldService(Event<ResponseEvent> responseEvent) {
this.responseEvent = responseEvent;
}
public void handleMessage(@Observes MessageEvent event) {
System.out.println("Received Message: " + event.getMessage());
responseEvent.fire(new ResponseEvent(event.getMessage()));
}
}
{code}
Results in stacktrace:
{code}
com.google.common.collect.ComputationException:

Thought it was a problem in our integration at first, but then I realized the problem
does not happen when field injection is used for the Event.
