ConcurrentMapFactory does not allow use of V8 maps with Sun JDK 6

Details

    Description

      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

         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();
         }
