+/**
+ * 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.
