 * An instance of {@code ThreadDeath} was originally specified to be thrown

 *
 * @deprecated {@link Thread#stop()} was originally specified to "stop" a victim
 *      thread by causing the victim thread to throw a {@code ThreadDeath}. It
 *      was inherently unsafe and deprecated in an early JDK release. The ability
 *      to "stop" a thread with {@code Thread.stop} has been removed and the
 *      {@code Thread.stop} method changed to throw an exception. Consequently,
 *      {@code ThreadDeath} is also deprecated, for removal.
