 103  * Persons not directly involved with maintaining the Java libraries or the
 104  * HotSpot VM can safely ignore the fact that a method is annotated with
 105  * {@code @HotSpotIntrinsicCandidate}.
 106  *
 107  * The HotSpot VM defines (internally) a list of intrinsics. Not all intrinsic
 108  * are available on all platforms supported by the HotSpot VM. Furthermore,
 109  * the availability of an intrinsic on a given platform depends on the
 110  * configuration of the HotSpot VM (e.g., the set of VM flags enabled).
 111  * Therefore, annotating a method with {@code @HotSpotIntrinsicCandidate} does
 112  * not guarantee that the marked method is intrinsified by the HotSpot VM.
 113  *
 114  * If the {@code CheckIntrinsics} VM flag is enabled, the HotSpot VM checks
 115  * (when loading a class) that (1) all methods of that class that are also on
 116  * the VM's list of intrinsics are annotated with {@code @HotSpotIntrinsicCandidate}
 117  * and that (2) for all methods of that class annotated with
 118  * {@code @HotSpotIntrinsicCandidate} there is an intrinsic in the list.
