Description

Similar to OFBIZ-3779, please consider upgrading the library used by UtilCache (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. 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. It also provides a near optimal eviction policy.
