----------------------------------------
I tried to add caffeine:3.1.1 and got this:

Required by:
project :

I tried to comment out related tasks. after 3 changes decided to stop.
It seems similar to https://github.com/ben-manes/caffeine/issues/716 but I have
not yet looked into details

> Key: OFBIZ-6747
> URL: https://issues.apache.org/jira/browse/OFBIZ-6747
> Project: OFBiz
> Issue Type: Task
> Components: ALL COMPONENTS
> Reporter: Ben Manes
> Assignee: Jacques Le Roux
> Priority: Minor
>
> 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.
