Ben Manes commented on OFBIZ-6747:
----------------------------------
{quote}We run under Java 11, but the build requires Java 8, right?
{quote}
Yes, in your build file it specifies {{{}targetCompatibility = '1.8'{}}}. Since
Caffeine v3.x targets 11 it fails when Gradle inspects their module metadata
rather that at compile / runtime due to an unsupported class file version.
Unfortunately the error messages are not very clear and I even ran into a
dependency's
[mismatch|https://github.com/tbroyer/gradle-errorprone-plugin/issues/73]
yesterday.
The {{:}} is short for the root project, so a subproject would be
{{:applications:workeffort}} (via {{{}gradlew projects{}}}). In your setup I
think it is applied everywhere.
{quote}Also we are somehow stuck with solr-core 8
{quote}
fwiw, Solr 8.3 adopted Caffeine and removed their custom caches in 9.0.

> 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.
