public class StickyMSCollector
extends MSCollector

This class implements per-collector thread behavior and state for the StickMS plan, which implements a generational sticky mark bits mark-sweep collector.

Specifically, this class defines StickyMS collection behavior (through trace and the collectionPhase method).
