035:         *
036:         * <p>CronTrigger itself is already a JavaBean but lacks sensible defaults.
037:         * This class uses the Spring bean name as job name, the Quartz default group
038:         * ("DEFAULT") as job group, the current time as start time, and indefinite
039:         * repetition, if not specified.
040:         *
041:         * <p>This class will also register the trigger with the job name and group of
042:         * a given {@link org.quartz.JobDetail}. This allows {@link SchedulerFactoryBean}
043:         * to automatically register a trigger for the corresponding JobDetail,
044:         * instead of registering the JobDetail separately.
045:         *
046:         * <p><b>NOTE:</b> This convenience subclass does not work with trigger
047:         * persistence in Quartz 1.6, due to a change in Quartz's trigger handling.
048:         * Use Quartz 1.5 if you rely on trigger persistence based on this class,
049:         * or the standard Quartz {@link org.quartz.CronTrigger} class instead.
