Fixed bean scopes to force singleton scopes. Better exception message for failed command validation. Fixed a bug in the Guava Event bus service. Added a new interface to throw events when a command is successful or failed.

public interface EventThrower {

    /**
     * Event on failure.
     *
     * @return the event that should be thrown (null does not send event)
     */
    Object eventOnFailure(Throwable failure);

    /**
     * Event on success.
     *
     * @param result
     *            the result
     * @return the event that should be thrown (null does not send event)
     */
    Object eventOnSuccess(Object result);
}

Added a new annotation to return an event rather than a value in a CommandServiceSpec

@CommandService
@ReturnEventOnSuccess
public class NotifyCrawlStatusCommandHandler
	implements CommandServiceSpec<NotifyCrawlStatusCommand, EventCrawlStatusUpdated> {
