The cron scheduled task stops running one hour before the DST ends

[TwilightPureDrm]

When I configure a scheduled task to run every 15 seconds through the Spring configuration file, the scheduled task stops running one hour before the end of daylight saving time.

<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="quartzTrigger" />
        </list>
    </property>
</bean>

<bean id="quartzTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="cronExpression" value="*/15 * * * * ?"/>
    <property name="jobDetail" ref="quartzJob"/>
    <property name="misfireInstruction" value="2"></property>
</bean>
<bean id="quartzJob" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
    <property name="jobClass" value="quartz.RollOverTaskService"/>
    <property name="durability" value="true"/>
</bean>

quartz version is 2.4.0-rc2
Is this a bug or normal?
