Jacques Le Roux commented on OFBIZ-6747: ---------------------------------------- Thanks for targetCompatibility info. As I said I'm far from a Gradle specialist :/ So 3.1.1 compiles when using sourceCompatibility = '11' targetCompatibility = '11' Not even a problem with solr-core. We are already running all our branches with Java 11. Remains solr-core but that's another issue (with also our LDAP plugin that says: bq. pluginLibsCompile 'org.apereo.cas:cas-server-support-ldap-core:5.0.10' // 6.4.0 declares an API of a component compatible with Java 11 and the consumer needed a runtime of a component compatible with Java 8) > 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).
