public class CaffeineLRUCache<K,​V>
extends Object
implements org.apache.camel.support.LRUCache<K,​V>, com.github.benmanes.caffeine.cache.RemovalListener<K,​V>, Serializable
    Deprecated.
    A cache that uses a near optional LRU Cache.

    The Cache is implemented by Caffeine which provides an efficient cache.

    If this cache stores Service then this implementation will on eviction invoke the Service.stop() method, to auto-stop the service.

    Use LRUCacheFactory to create a new instance (do not use the constructor).
