Description

The ServicePool or (DefaultServicePool in 2.x) uses a unbounded ConcurrentHashMap to cash producers. This can cause memory leaks in highly dynamic routes using recipient lists creating many temporary endpoint which will never be evicted even when the route stops. Even though workarounds exists, we might consider using an LRUCache for eviction.
