JavaEE 6中的异步方法

Question

我尝试在JavaEE 6中使用异步方法。我创建了以下类。但是，输出日志的结果是同步。这不对。

   @javax.ejb.Stateless
    public class MailManager implements Serializable{
    @Asynchronous
        public void send(List<String> toList, Mail mail, final SystemSetting systemSetting) throws MailException, UnsupportedEncodingException{

            boolean isError = false;
            for(InternetAddress addr :addressList){
                    MimeMessage msg = getMimeMessage(addr, mail, session);
                    Transport.send(msg);
                    log.info("Sent email to ["+addr+"].");
            }
            if(isError){
                throw new MailException("Mail sending error occurred. Check error log.");
            }
            log.debug("Async finish.");
        }
    }

ManagedBean

@Named
@SessionScoped
public class MailController extends AbstractController{
    @Inject @new(MailCreater.class)
    private MailFactory mailCreater;

    @Inject
    private MailManager mailManager;

    public void send(){
        Mail mail = null;
            mail = mailCreater.createFromTemplate(this, false,
                    mimeInfo, "template/testTemplate.txt","template/FOOTER1.body", map);
            mailManager.send(list, mail, systemSetting);
        log.debug("send() finish.");
    }
}

日志

INFO[Log4jLogger] - Sent email to [test1@test.co.jp].
INFO [Log4jLogger] - Sent email to [test2@test.co.jp].
.
.
.
DEBUG [Log4jLogger] - Async finish.
DEBUG [Log4jLogger] - send() finish.

更新

将@Inject更改为@EJB

时的错误代码
