+/**
+ * A method type represents the arguments and return type accepted and
+ * returned by a method handle, or the arguments and return type passed
+ * and expected  by a method handle caller.  Method types must be properly
+ * matched between a method handle and all its callers,
+ * and the JVM's operations enforce this matching at, specifically
+ * during calls to {@code MethodHandle#invokeExact MethodHandle.invokeExact}
+ * and {@code MethodHandle#invoke MethodHandle.invoke}, and during execution
+ * of {@code invokedynamic} instructions.
+ * <p>
+ * The structure is a return type accompanied by any number of parameter types.
+ * The types (primitive, {@code void}, and reference) are represented by {@link Class} objects.
+ * (For ease of exposition, we treat {@code void} as if it were a type.
+ * In fact, it denotes the absence of a return type.)
+ * <p>
+ * All instances of {@code MethodType} are immutable.
+ * Two instances are completely interchangeable if they compare equal.
+ * Equality depends on pairwise correspondence of the return and parameter types and on nothing else.
+ * <p>
+ * This type can be created only by factory methods.
+ * All factory methods may cache values, though caching is not guaranteed.
+ * Some factory methods are static, while others are virtual methods which
+ * modify precursor method types, e.g., by changing a selected parameter.
+ * <p>
+ * Factory methods which operate on groups of parameter types
+ * are systematically presented in two versions, so that both Java arrays and
+ * Java lists can be used to work with groups of parameter types.
+ * The query methods {@code parameterArray} and {@code parameterList}
+ * also provide a choice between arrays and lists.
+ * <p>
+ * {@code MethodType} objects are sometimes derived from bytecode instructions
+ * such as {@code invokedynamic}, specifically from the type descriptor strings associated
+ * with the instructions in a class file's constant pool.
+ * <p>
+ * Like classes and strings, method types can also be represented directly
+ * in a class file's constant pool as constants.
+ * A method type may be loaded by an {@code ldc} instruction which refers
+ * to a suitable {@code CONSTANT_MethodType} constant pool entry.
+ * The entry refers to a {@code CONSTANT_Utf8} spelling for the descriptor string.
+ * (For full details on method type constants,
+ * see sections 4.4.8 and 5.4.3.5 of the Java Virtual Machine Specification.)
+ * <p>
+ * When the JVM materializes a {@code MethodType} from a descriptor string,
+ * all classes named in the descriptor must be accessible, and will be loaded.
+ * (But the classes need not be initialized, as is the case with a {@code CONSTANT_Class}.)
+ * This loading may occur at any time before the {@code MethodType} object is first derived.

+/**
+ * A field may be annotated as stable if all of its component variables
+ * changes value at most once.
+ * A field's value counts as its component value.
+ * If the field is typed as an array, then all the non-null components
+ * of the array, of depth up to the rank of the field's array type,
+ * also count as component values.
+ * By extension, any variable (either array or field) which has annotated
+ * as stable is called a stable variable, and its non-null or non-zero
+ * value is called a stable value.
+ * <p>
+ * Since all fields begin with a default value of null for references
+ * (resp., zero for primitives), it follows that this annotation indicates
+ * that the first non-null (resp., non-zero) value stored in the field
+ * will never be changed.
+ * <p>
+ * If the field is not of an array type, there are no array elements,
+ * then the value indicated as stable is simply the value of the field.
+ * If the dynamic type of the field value is an array but the static type
+ * is not, the components of the array are <em>not</em> regarded as stable.
+ * <p>
+ * If the field is an array type, then both the field value and
+ * all the components of the field value (if the field value is non-null)
+ * are indicated to be stable.
+ * If the field type is an array type with rank {@code N &gt; 1},
+ * then each component of the field value (if the field value is non-null),
+ * is regarded as a stable array of rank {@code N-1}.
+ * <p>
+ * Fields which are declared {@code final} may also be annotated as stable.
+ * Since final fields already behave as stable values, such an annotation
+ * indicates no additional information, unless the type of the field is
+ * an array type.
+ * <p>
+ * It is (currently) undefined what happens if a field annotated as stable
+ * is given a third value.  In practice, if the JVM relies on this annotation
+ * to promote a field reference to a constant, it may be that the Java memory
+ * model would appear to be broken, if such a constant (the second value of the field)
+ * is used as the value of the field even after the field value has changed.
