Review comment:
The easiest implementation of an LRU cache in Java would be using
https://docs.oracle.com/javase/8/docs/api/java/util/LinkedHashMap.html#removeEldestEntry-java.util.Map.Entry-
with `Collections.synchronizedMap()`. For a more sophisticated cache, copying
some code from commons-collections could be done.
