libcaffeine-java binary package in Ubuntu Oracular s390x

 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
