InstSize:
	Size of each object instance of the Java class.

InstCount:
	Number of object instances of the Java class.

InstBytes:
	This is usually (InstSize * InstNum). The only exception is java.lang.Class,
	whose InstBytes also includes the slots used to store static
	fields. InstBytesi is not counted in ROAll, RWAll or Total.

Mirror:
	Size of the Klass::java_mirror() object.

KlassBytes:
	Size of the InstanceKlass or ArrayKlass for this class. Note
	that this includes VTab, ITab, OopMap.

K_secondary_supers:
	Number of bytes used by the Klass::secondary_supers() array.

VTab:
	Size of the embedded vtable in InstanceKlass.

ITab:
	Size of the embedded itable in InstanceKlass.

OopMap:
	Size of the embedded nonstatic_oop_map in InstanceKlass.

IK_methods:
	Number of bytes used by the InstanceKlass::methods() array.

IK_method_ordering:
	Number of bytes used by the InstanceKlass::method_ordering()
	array.

IK_local_interfaces:
	Number of bytes used by the InstanceKlass::local_interfaces()
	array.

IK_transitive_interfaces:
	Number of bytes used by the InstanceKlass::transitive_interfaces()
	array.

IK_fields:
	Number of bytes used by the InstanceKlass::fields() array.

IK_inner_classes:
	Number of bytes used by the InstanceKlass::inner_classes() array.

IK_signers:
	Number of bytes used by the InstanceKlass::singers() array.

class_annotations:
	Size of class annotations.

fields_annotations:
	Size of field annotations.

methods_annotations:
	Size of method annotations.

methods_parameter_annotations:
	Size of method parameter annotations.

methods_default_annotations:
	Size of methods default annotations.

type_annotations:
	Size of type annotations.

annotations:
	Size of all annotations.

Cp:
	Size of InstanceKlass::constants().

CpTags:
	Size of InstanceKlass::constants()->tags().

CpCache:
	Size of InstanceKlass::constants()->cache().

CpOperands:
	Size of InstanceKlass::constants()->operands().

CpRefMap:
	Size of InstanceKlass::constants()->reference_map().

CpAll:
	Sum of Cp + CpTags + CpCache + CpOperands + CpRefMap.

MethodCount:
	Number of methods in this class.

MethodBytes:
	Size of the Method object.

Constmethod:
	Size of the ConstMethod object.

Methoddata:
	Size of the MethodData object.

Stackmap:
	Size of the stackmap_data.

Bytecodes:
	Of the "MethodBytes" column, how much are the space taken up
	by bytecodes.

MethodAll:
	Sum of MethodBytes + Constmethod + Stackmap + Methoddata.

ROAll:
	Size of all class meta data that could (potentially) be placed
	in read-only memory. (This could change with CDS design).

RWAll:
	Size of all class meta data that must be placed in read/write
	memory. (This could change with CDS design) .

Total:
	ROAll + RWAll. Note that this does NOT include InstBytes..
