Internal error on DateEvent capture events in v11.1.2

Hi there I am sorry but I may have found an error on version 11.1.2. I have a scenario that captures 2 events based on date, one at the beginning of the propagation and one at the end using TLE propagation. The test I have was successful with version 11.1, while it fails with version 11.1.2

Here the test.

    // TLE
    val tleOrbit = new OrbitElement(
        "1 43197U 18015F   19284.07336221  .00000533  00000-0  24811-4 0  9998",
        "2 43197  97.4059  50.1428 0017543 265.5429 181.0400 15.24136761 93779");

    // startTime, endTime
    val start = 1570802400000L;
    val end = 1570838399000L;

    //Build propagator
    TLE tle = new TLE("1 43197U 18015F   19284.07336221  .00000533  00000-0  24811-4 0  9998",
        "2 43197  97.4059  50.1428 0017543 265.5429 181.0400 15.24136761 93779");
    Propagator propagator = TLEPropagator.selectExtrapolator(tle);

    //Create logger
    EventsLogger orbitalLogger = new EventsLogger();
    //Max check to seconds
    int maxCheck = (int) ((end - start) / 2000);
    DateDetector dateDetector = new DateDetector(
        maxCheck ,
        oneMicrosInSec,
        Time.getAbsoluteDateFromTimestamp(start))
        .withHandler(new GenericEventHandler<>());
    dateDetector.addEventDate(Time.getAbsoluteDateFromTimestamp(end));

    //Add event detectors to orbit
    propagator.addEventDetector(orbitalLogger.monitorDetector(dateDetector));

    //Propagate
    SpacecraftState lastState = propagator.propagate(
        Time.getAbsoluteDateFromTimestamp(start),
        Time.getAbsoluteDateFromTimestamp(end).shiftedBy(1));

where

public static AbsoluteDate getAbsoluteDateFromTimestamp(long timestamp) {
    LocalDateTime utcDate = LocalDateTime.ofInstant(Instant.ofEpochMilli(timestamp), UTC_ZONE_ID);
    val year = utcDate.getYear();
    val month = utcDate.getMonthValue();
    val day = utcDate.getDayOfMonth();
    val hour = utcDate.getHour();
    val minute = utcDate.getMinute();
    val second = utcDate.getSecond();
    val millis = utcDate.getNano() / 1e9;
    return new AbsoluteDate(year, month, day, hour, minute, second, TimeScalesFactory.getUTC()).shiftedBy(millis);

Here the error

The test fails due to:

• maxCheck big, half of the propagation period, set to speed up the calculation as I am interested only in first and last moments
• .shiftedBy(1) adding a second to the last timestamp so to extend the propagation period, so to capture with the event the last moment

The test does not fail if:

• I set the maxCheck to a smaller number (like 100 sec)
• I do not add the additional second
• I add a big interval to the last moment

I stated, this test was not failing with previous version.

Thanks for the follow up Kindly Alberto
