BusinessCelenderImpl can't calculate Business Date correctly

Solution In Progress - Updated -

Issue

When I test BusinessCalenderImpl like the following, it does not work as expected.

    @Test
    public void testCalculateMinutesPassingOverHolidays() {
        Properties config = new Properties();
        config.setProperty(BusinessCalendarImpl.DAYS_PER_WEEK, "5");
        config.setProperty(BusinessCalendarImpl.HOURS_PER_DAY, "8");
        config.setProperty(BusinessCalendarImpl.START_HOUR, "9");
        config.setProperty(BusinessCalendarImpl.END_HOUR, "18");
        config.setProperty(BusinessCalendarImpl.WEEKEND_DAYS, "1,7"); // sun,sat
        config.setProperty(BusinessCalendarImpl.HOLIDAYS, "2018-04-30,2018-05-03,2018-05-04,2018-05-05");
        config.setProperty(BusinessCalendarImpl.HOLIDAY_DATE_FORMAT, "yyyy-MM-dd");
        String expectedDate = "2018-05-08 13:00"; // 5/1 -> 5/2 -> 5/7 -> 5/8

        SessionPseudoClock clock = new StaticPseudoClock(parseToDateWithTime("2018-05-01 13:00").getTime());
        BusinessCalendarImpl businessCal = new BusinessCalendarImpl(config, clock);


        Date result = businessCal.calculateBusinessTimeAsDate("P3D");

        assertEquals(expectedDate, formatDate("yyyy-MM-dd HH:mm", result));
    }

In this example, it calculates business time at 2018-05-01 13:00 with 3 days (P3D) duration.
Expected date and time is 2018-05-08 13:00 as from 5/3 to 5/5 are holiday and 5/6 is Sunday.
But it's returns '2018-05-07 13:00'. Is this a bug?
