   * <p>Note, however, that although multiple locks can be created for a given Enum value, whether
   * it be through separate factory instances or through multiple calls to the same factory,
   * attempting to acquire multiple locks with the same Enum value (within the same thread) will
   * result in an IllegalStateException regardless of the factory's policy. For example:
   *
   * {@snippet :

    arraycopy(array, 0, dst, dstOff, size);
    return dstOff + size;
  }

  // The fake cast to E is safe because the creation methods only allow E's
