[infinispan-issues] [JBoss JIRA] (ISPN-2237) ConcurrentMapFactory does not allow use of V8 maps with Sun JDK 6

ConcurrentMapFactory does not allow use of V8 maps with Sun JDK 6 ----------------------------------------------------------------- Key: ISPN-2237 URL: https://issues.jboss.org/browse/ISPN-2237 Project: Infinispan Issue Type: Bug Affects Versions: 5.1.6.FINAL Reporter: Robert Stupp Assignee: Galder Zamarreño Fix For: 5.2.0.Alpha4, 5.2.0.Final The implementation in ConcurrentMapFactory checks for existance of a Sun JVM private class. But although a Sun JDK/JRE 6 is used, the check fails (wrong class com.sun.unsafe.Unsafe instead of sun.misc.Unsafe). Sould use sun.misc.Unsafe {noformat} 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(); } {noformat}
