    Description

      Today System.currentTimeMillis is used as the LRU component of the scoring function for eviction. currentTimeMillis() returns the time spent from epoch in milliseconds. As time passes, currentTimeMillis() returns bigger values – which can impact the scoring (as weights stay constant).
