Jacques Le Roux commented on OFBIZ-6747: ---------------------------------------- Hi Ben, I'm still not sure to understand the reason we need 2.9.3. We run under Java 11, but the build requires Java 8, right? Something I don't understand is the 1st block of error {quote} > Could not resolve com.github.ben-manes.caffeine:caffeine:3.1.1. Required by: project : > No matching variant of com.github.ben-manes.caffeine:caffeine:3.1.1 was found. {quote} "project" is empty. I guess it means the whole project (ie ofbiz), right? Also we are somehow stuck with solr-core 8 (OFBIZ-10633). {quote} So it works but I'm unsure of the situation. So I suggest for now to continue to use the 8 branch. {quote} Fortunately, as you said, we can live with CLHM for now, no hurry :) > Replace ConcurrentLinkedHashMap by Caffeine > ------------------------------------------- > > 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].
