SimpleMRUCache

public class SimpleMRUCache extends Object implements Serializable
Cache following a "Most Recently Used" (MRU) algorithm for maintaining a bounded in-memory size; the "Least Recently Used" (LRU) entry is the first available for removal from the cache.

This implementation uses a bounded MRU Map to limit the in-memory size of the cache. Thus the size of this cache never grows beyond the stated size.
