CDI API regression: Observes.notifyObserver has been changed to Observes.receive
--------------------------------------------------------------------------------

                 Key: WELD-699
                 URL: https://jira.jboss.org/browse/WELD-699
             Project: Weld
          Issue Type: Bug
          Components: CDI API
    Affects Versions: 1.1.0.Beta1
            Reporter: Sivakumar Thyagarajan


In the Weld 1.1 Beta 1 release, the @Observes API has an annotation element changed. This is an incompatible API change and would break existing clients.

-- The original API for @Observes --
public interface javax.enterprise.event.Observes extends java.lang.annotation.Annotation{
    public abstract javax.enterprise.event.Reception notifyObserver();
    public abstract javax.enterprise.event.TransactionPhase during();
}
-- The original API for @Observes --

and now it is:
-- The new API for @Observes --
public interface javax.enterprise.event.Observes extends java.lang.annotation.Annotation{
    public abstract javax.enterprise.event.Reception receive();
    public abstract javax.enterprise.event.TransactionPhase during();
}
-- The new API for @Observes --

Notice the renaming of "notifyObserver" to "receive". The original name for the annotation element "notifyObserver" has been published earlier as part of Java EE 6 javadoc [1]. However in the JSR 299 specification, the annotation element is referred to as "receives" (See Section 10.4.3) and hence I think this have been renamed as part of WELD-455 [2]. 

Please revert this change in API.
