public class StickyImmixCollector
extends ImmixCollector

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

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