LRU (Least Recently Used) algorithm for the cache.

Since release 2.3 this class requires Java 1.4 to use the LinkedHashSet. Use prior OSCache release which require the Jakarta commons-collections SequencedHashMap class or the LinkedList class if neither of the above classes are available.

No synchronization is required in this class since the AbstractConcurrentReadCache already takes care of any synchronization requirements.
