Java 24 to Reduce Object Header Size and Save Memory

JEP 450 (Compact Object Headers) has been targeted for delivery in JDK 24. This currently experimental feature optimizes heap utilization by shrinking the size of the mandatory object header in HotSpot. This should reduce overall heap size, improve density of deployments, and increase data locality.
