Description

The StandardProcessScheduler has a map that it holds internally to map processors to their LifecycleState. When a processor is removed from the canvas, it is not removed from the map. LifecycleState is a fairly lightweight object, so this isn't likely to cause problems unless constantly adding and removing components. However, it certainly needs to be addressed.
