@Deprecated
    public static void validateSideEffectValue(final Object value) throws IllegalArgumentException {
        if (null == value)
            throw TraversalSideEffects.Exceptions.sideEffectValueCanNotBeNull();
    }
@deprecated As of release 3.5.3, not replaced as there is really no general validation anymore for values since
{@code null} is now accepted.
