59851: Merged BRANCHES/DEV/mward/head_bf_gdata_upgd to BRANCHES/DEV/HEAD-BUG-FIX (local cache improvements):
59586: DefaultSimpleCache max size is Integer.MAX_VALUE when configured with maxItems of 0.
59590: maxItems for DefaultSimpleCache is now an optional feature.
59592: non-clustered caches will not use size-based eviction when {cacheName}.eviction-policy=NONE, to match clustered caches.
59594: Added TTL to DefaultSimpleCache - not yet configurable through the factory.
59602: DefaultCacheFactory can create caches with a time-to-live setting enabled.
59620: Organise imports for DefaultSimpleCache
59622: DefaultSimpleCache: changed field name from map to cache, as this makes more sense with changing to use of CacheBuilder.
59627: Added maxIdleSecs property to DefaultSimpleCache - not yet configurable from the cache factory.
59629: DefaultCacheFactory now supports maxIdleSeconds property for configuring non-clustered caches.
59633: Updated description of supported non-clustered cache properties in caches.properties
