You can just a single one... the ActiveMQScheduledComponent uses an
executor... once the timer is reached.. it will call the executor...
I would be careful on adding a lot of threads on the broker...
Try reusing the already existent ShceduledExecutor...
if you at least reuse the component it's easier to change it IMO.---
