- * 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. - *

- * 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 not regarded as stable. - *

- * 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 > 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}. - *

- * 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. - *

- * 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. - */ -/* package-private */ -@Target(ElementType.FIELD) -@Retention(RetentionPolicy.RUNTIME) -@interface Stable { -}
