Jacques Le Roux commented on OFBIZ-6747:
----------------------------------------
Thanks for the tip was useful in one case (getServiceLogMap). Else I simply
used Cache class when creating.
> Replace ConcurrentLinkedHashMap by Caffeine

> Key: OFBIZ-6747
> URL: https://issues.apache.org/jira/browse/OFBIZ-6747
> Project: OFBiz
> Issue Type: Improvement
> Components: framework/base, framework/service
> Affects Versions: Upcoming Branch
> Reporter: Ben Manes
> Assignee: Jacques Le Roux
> Priority: Minor
> Fix For: Upcoming Branch
>
>
> 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.
