Description

ResponseCachingPolicy uses 2 HashSets containing a few Integers each for matching int values.

This involves lots of boxing plus the overhead of the hashSet.

Since the numbers of integers involved is very small - at most 6 - it seems unnecessary to use hashing. A linear search would likely be quicker.

If the number of entries were to be rather larger, then Arrays#binarySearch might be better.
