-----------------------------------
Summary: CronParser.getNextScheduledTime() with dayOfMonth and
dayOfWeek
Key: AMQ-6217
URL: https://issues.apache.org/jira/browse/AMQ-6217
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.13.2, 5.12.2
Environment: Windows Java 1.8
Reporter: Rafael Fuentes
When we try to get several “NextSecheduledTime” for a cron string that have set
the “day of month” and the “day of week “at the same time, CronParser returns
“days of month” that do not match with the defined “days of week”.
For example:
public static void main(String[] args){
try
{
DateFormat format = new SimpleDateFormat("yyyy/MM/dd");
Date executionDate = format.parse("2016/09/11");
Date end = format.parse("2016/10/31");
String cron ="45 6 1,2,3,4,5,6,7,8,9,10,11 * 1,2,3,4,5";
executionDate = new Date(CronParser.getNextScheduledTime(cron,
executionDate.getTime()));
while (executionDate.compareTo(end) < 0) {
System.out.println(executionDate);
executionDate = new Date(CronParser.getNextScheduledTime(cron,
executionDate.getTime()));
}
}
catch(Exception e)
{ e.printStackTrace(); }
}
This outputs:
Sun Oct 02 06:45:00 CEST 2016
Mon Oct 03 06:45:00 CEST 2016
Tue Oct 04 06:45:00 CEST 2016
Wed Oct 05 06:45:00 CEST 2016
Thu Oct 06 06:45:00 CEST 2016
Fri Oct 07 06:45:00 CEST 2016
Mon Oct 10 06:45:00 CEST 2016
Tue Oct 11 06:45:00 CEST 2016
Cron string defines “Monday to Friday” but CronParser returns “Sunday”.
I think it shouldn’t return Sunday, it should start on Mon Oct 03.
