After setting the ejb-timer-service property minimum-delivery-interval to 9000, an attempt to set the ejb-timer-service property redelivery-interval-in-mills to 7000 causes the set command to fail with the following error:
[echo] Doing admin task set [exec] [Attribute(id=redelivery-interval-internal-in-millis) : Redelivery-Interval (7,000) should be greater than or equal to Minimum-delivery-interval- in-millis (9,000)] [exec] CLI137 Command set failed.
minimum-delivery-interval is the minimal interval duration between deliveries of the same periodic timer.
redelivery-interval-in-mills is the time the timer service will wait after a failed ejbTimeout before attempting redelivery.
The problem is that the logic that relates the redelivery interval property to the minimum delivery property is incorrect and prevents you from using the GUI or the CLI to set any value where the minimum delivery interval is greater than redelivery interval.
The minimum-delivery-interval-in-millis must always be set equal to or higher than ejb-timer-service property redelivery-interval-in-millis. The problem is that there is an erroneous validation check in the aerver to verify that the value for redelivery-interval-in-millis is greater than the value for minimum-delivery-interval-in-millis.
