      Description

      When a concurrent GC is in use (G1 or CMS), we must generate store_release instructions when setting an object's klass field.

      The runtime was updated to store_release instructions when creating objects through the slow path and to do load_acquire instructions when reading the klass field from concurrent readers See JDK-8160369 and sub-tasks.
