penalty for accessing forwarded objects involved resolving through the forwarding pointer, until the Update References phase fixed the affected references. A more efficient implementation ships now, where LRB self-fixes the forwarded reference on the same code path, eliminating continuous resolves for potentially hot accesses. Self-fixing is implemented for C1 and C2 (JDK-8231087), interpreter (JDK-8232992) and runtime (JDK-8232010) barriers.
