  Description     : High performance caching library

Caffeine provides an in-memory cache using a Google Guava inspired API.
The improvements draw on the experience designing Guava's cache and
ConcurrentLinkedHashMap.

Caffeine provides flexible construction to create a cache with a combination
of the following features:
 * Automatic loading of entries into the cache, optionally asynchronously
 * Size-based eviction when a maximum is exceeded based on frequency and recency
 * Time-based expiration of entries, measured since last access or last write
 * Asynchronously refresh when the first stale request for an entry occurs
 * Keys automatically wrapped in weak references
 * Values automatically wrapped in weak or soft references
 * Notification of evicted (or otherwise removed) entries
 * Writes propagated to an external resource
 * Accumulation of cache access statistics

This library is a new dependency of Apache JMeter (packaged as jakarta-jmeter).
It'll be maintained by the Java Team.
