 * Utility class for detecting inadvertent uses of boxing in

 * whether the system property {@code org.openjdk.java.util.stream.tripwire} is
 * considered {@code true} according to {@link Boolean#getBoolean(String)}.
 * This should normally be turned off for production use.
 *
 * @apiNote
 * Typical usage would be for boxing code to do:
 * {@code
 *     if (Tripwire.ENABLED)
 *         Tripwire.trip(getClass(), "{0} calling PrimitiveIterator.OfInt.nextInt()");
 * }
