public class	IntegerEnum A class enabling simple construction of type-safe integer enumerations
public class	Interval
public class	IntervalNode
public class	IntervalTree
public class	KlassArray
public class	LivenessAnalysis Finds all paths from roots to the specified set of objects.
public class	LivenessPath Describes a path from an object back to the root which is keeping it alive.
public class	LivenessPathElement Describes an element in a `sun.jvm.hotspot.utilities.LivenessPath`.
public class	LivenessPathList Simple container class for LivenessPaths
public class	MarkBits Helper class which covers the reserved area of the heap with an (object-external) set of mark bits, used for GC-like scans through the heap like liveness analysis.
public class	MessageQueueBackend
public class	MethodArray
public class	ObjectReader ObjectReader can "deserialize" objects from debuggee.
public class	Observable References Deprecated `Observable` is deprecated or references (maybe indirectly) at least one deprecated element.
public class	PlatformInfo Provides canonicalized OS and CPU information for the rest of the system.
public class	PointerFinder This class, only intended for use in the debugging system, provides the functionality of find() in the VM.
public class	PointerLocation This class attempts to describe possible locations of pointers in the VM.
public class	ProcImageClassLoader Class loader that loads classes from the process/core image of the debuggee.
public class	ProgressiveHeapVisitor This class wraps a user's chosen HeapVisitor with the functionality that a chosen "thunk" is called periodically during the heap traversal.
public class	RBColor Type-safe enum for the colors in a red-black tree.
public class	RBNode This class implements a node in a red-black tree.
public class	RBTree
public class	ReversePtrs ReversePtrs hashtable.
public class	ReversePtrsAnalysis For a set of known roots, descends recursively into the object graph, for each object recording those objects (and their fields) which point to it.
public class	RobustOopDeterminator This class determines to the best of its ability, and in a reasonably robust fashion, whether a given pointer is an intact oop or not.
public class	StreamMonitor Reads all of the data from the given InputStream, and allows the caller to wait for a given string to come in or watch for many possible strings.
public class	SystemDictionaryHelper
public class	U1Array
public class	U2Array
public class	U4Array
public class	Unsigned5 Decompression algorithm from utilities/unsigned5.hpp.
public class	UnsupportedPlatformException
public class	WorkerThread This class abstracts the notion of a worker thread which is fed tasks in the form of Runnables.
