MSC000001: 无法启动 Schedule 类型的服务

Question

我正在重构一个 class 负责执行计划的作业。所以，我刚刚删除了一个方法，现在 .ear 工件没有部署。

原文class：

@Stateless(name = "jobScheduleService")
public class JobScheduleService {

    @Inject
    private FormService formService;;

    @EJB
    private EliminationService eliminationService;

    @Schedules({
            @Schedule(hour = "23", minute = "50")
    })
    public void remind() throws MessagingException {
        formService.sendDeadlineReminder();
    }

    @Schedules({
            @Schedule(hour = "2", minute = "00")
    })
    public void eliminatesOutOfDate() {
        this.eliminationService.eliminatesOutOfDate();
    }
}

Class 删除了 eliminatesOutOfDate() 方法：

@Stateless(name = "jobScheduleService")
public class JobScheduleService {

    @Inject
    private FormService formService;

    @Schedules({
            @Schedule(hour = "23", minute = "50")
    })
    public void remind() throws MessagingException {
        formService.sendDeadlineReminder();
    }
}

堆栈跟踪:

我不明白为什么会出现异常。
