Spring @Scheduled cron issue with "every x and y minute"

Hello, All my cron are working well except this one with "every x and y minute" I'm using Spring Boot 2.5.4

I tried this : @Scheduled(cron = "0 5,10 5-23 * * *", zone = "Europe/Paris")

The cron task is executed every minute, it's like i wrote "0 * 5-23 * * *" So we can use a coma for hours (like I saw in the documentation) but not for minutes ?

The solution I found is to use multiple tasks @Scheduled(cron = "0 5 5-23 * * *", zone = "Europe/Paris") @Scheduled(cron = "0 10 5-23 * * *", zone = "Europe/Paris")

It works but I think it will cause issues if the tasks are too long or too close to eachother

I used Spring Boot 2.5.4, and test using your setting @Scheduled(cron = "0 5,10 5-23 * * *", zone = "Europe/Paris"). but It only executed for exactly 5, 10 minutes.

We have CronExpressionTests. I can write the following for the exact scenario and it passes:

@Test
void specificMinutesAndHours() {
    CronExpression expression = CronExpression.parse("0 5,10 5-23 * * *");

    LocalDateTime last = LocalDateTime.now().withHour(5).withMinute(1);
    LocalDateTime expected = last.withMinute(5).withSecond(0).withNano(0);
    LocalDateTime actual = expression.next(last);

    assertThat(actual).isNotNull();
    assertThat(actual).isEqualTo(expected);

    last = LocalDateTime.now().withHour(5).withMinute(5).withSecond(1);
    expected = last.withMinute(10).withSecond(0).withNano(0);
    actual = expression.next(last);

    assertThat(actual).isNotNull();
    assertThat(actual).isEqualTo(expected);

    last = LocalDateTime.now().withHour(5).withMinute(10).withSecond(1);
    expected = last.withHour(6).withMinute(5).withSecond(0).withNano(0);
    actual = expression.next(last);

    assertThat(actual).isNotNull();
    assertThat(actual).isEqualTo(expected);
}

You will need to provide a failing test or sample that demonstrates the issue.
