如何解决pauseJob，resumeJob执行多次后的问题？

Question

JobDetail jobDetail = JobBuilder.newJob(QuartzStudy.class).withIdentity("job1").build();
    CronTrigger trigger = TriggerBuilder.newTrigger()
            .startAt(DateBuilder.evenSecondDate(new Date()))
            .withSchedule(CronScheduleBuilder.cronSchedule("*/5 * * * * ?").withMisfireHandlingInstructionDoNothing())
            .build();
    scheduler.scheduleJob(jobDetail, trigger);
    Thread.sleep(10000);
    scheduler.pauseJob(jobDetail.getKey());
    Thread.sleep(10000);
    scheduler.resumeJob(jobDetail.getKey());

暂停作业后，Thead睡眠10s，然后恢复作业，但执行多次
