The eviction of entries in software caches is meant to limit the cache's total memory footprint. We observe that if an evicted entry is in-use, or reachable, elsewhere in the program, then said eviction will have a negilible reduction in memory usage. Worse yet, a subsequent request for the evicted entry could result in the creation of a duplica…

FinalCache uses LRU to evict entries. However it does not use access-history to compute LRU. Rather when objects become unused they become managed by LRU. Usage is determined by the garbage collector.
