> Similar to OFBIZ-3779, please consider upgrading the library used by [UtilCache|https://github.com/apache/ofbiz/blob/trunk/framework/base/src/main/java/org/apache/ofbiz/base/util/cache/UtilCache.java] (v1.2). The current version is 1.4.2 and is the last major release planned.
> The preferable alternative would be to upgrade to [Caffeine|https://github.com/ben-manes/caffeine]. This is a Java 8 rewrite based on what I've learned since developing CLHM and Guava's cache. As expected it provides [superior performance|https://github.com/ben-manes/caffeine/wiki/Benchmarks]. It also provides a [near optimal|https://github.com/ben-manes/caffeine/wiki/Efficiency] eviction policy.
