[ https://issues.jboss.org/browse/AS7-3119?page=com.atlassian.jira.plugin.s... ] Carlo de Wolf commented on AS7-3119: ------------------------------------ EJB EG Oct 31 2007: {quote} 2. Overlapping timer callbacks The original EJB Timer Service was aimed at modeling coarse-grained business processes. The spec states that such events are expected to correspond to hours, days, or longer periods of time. As such, it did not fully specify the runtime behavior for some timer callback issues that are more likely to arise with much finer-grained timeouts. Namely, what happens if a callback for a repeating timer is still processing when the next callback is scheduled to occur? One aspect of this issue is whether it's ok to discard such pending callbacks. Another is whether multiple overlapping callbacks for the same timer should be delivered concurrently or sequentially. One suggestion we discussed for handling part of the overlapping issue is a "backlog" field that would specify the number of overlapping callbacks to allow before the container begins to discard. Another item worth mentioning is the EJB specification does address a related issue regarding server crash/shutdown. If the container is not running when a timer would have expired, the container is required to invoke the timer's callback method during container restart. In the case of an interval timer the current spec only requires the container to deliver at least one missed expiration. {quote} -- This message is automatically generated by JIRA.
