> When a job needs to be retried, a new Timer with a single TimerTask is created. As each Timer creates a controlling thread, a large number of jobs to be retried can lead to the creation of a large amount of threads. This number is unlimited.
> To control the amount of threads created under such circumstances, a ScheduledThreadPoolExecutor should be used, for which we can control the number of threads. Each Job Queue should get its own dedicated instance of such an executor.
