add log.info when using backported concurrent hash map ------------------------------------------------------ Key: ISPN-2851 URL: https://issues.jboss.org/browse/ISPN-2851 Project: Infinispan Issue Type: Enhancement Components: Core API Affects Versions: 5.2.2.Final Reporter: Mathieu Lachance Assignee: Galder Zamarreño Priority: Minor Fix For: 6.0.0.Final it would be nice if there was a bit more logging information when using backported concurrent hash map since it is activation is not only based on the : Boolean.getBoolean("infinispan.unsafe.allow_jdk8_chm"); property as we could think. static { boolean sunIncompatibleJvm; boolean jdk8; boolean allowExperimentalMap = Boolean.getBoolean("infinispan.unsafe.allow_jdk8_chm"); try { Class.forName("com.sun.unsafe.Unsafe"); sunIncompatibleJvm = false; } catch (ClassNotFoundException e) { sunIncompatibleJvm = true; } try { Class.forName("java.util.concurrent.atomic.LongAdder"); jdk8 = true; } catch (ClassNotFoundException e) { jdk8 = false; } if (jdk8 || sunIncompatibleJvm || !allowExperimentalMap){ MAP_CREATOR = new JdkConcurrentMapCreator(); } else{ MAP_CREATOR = new BackportedV8ConcurrentMapCreator(); logger.info("using backported jdk8 concurrent hash map implementation"); } }
