public interface EventListenerProducer<T>
Allows do define custom producers for know EventListeners. Intention of this is that there might be several implementations that might provide different listener instance based on the context they are executed in.
It will be invoked by RegisterableItemsFactory implementation (especially InjectableRegisterableItemsFactory in CDI world) for every KieSession. Recommendation is to always produce new instances to avoid unexpected results.
