Spring Integration: Stopping a Poller after a fixed duration - spring-integration

Question

My requirement is that I would like to stop the poller after a fixed interval of time say 9 (hrs.). For now I am trying to stop the poller after 1 min. Following is my code:
<int-task:scheduler id="scheduler" pool-size="10"/>
<int-task:scheduled-tasks scheduler="scheduler">
<int-task:scheduled ref="incomingFiles.adapter" method="stop" fixed-delay="#{10 * 1000}"/>
</int-task:scheduled-tasks>
But now what I observe is that when I start my program then on startup I immediately get the message in the console as:

Somewhere in the start of the starttup logs we get:
May 28, 2014 10:27:55 AM
org.springframework.integration.endpoint.AbstractE ndpoint start INFO:
started incomingFiles.adapter
Somewhere in the end of the startup logs we get:
May 28, 2014 10:27:55 AM
org.springframework.integration.endpoint.AbstractE ndpoint stop INFO:
stopped incomingFiles.adapter
Why the incomingFiles.adapter has been stopped immediately while our fixed-delay="#{10 * 1000}" is 10 sec. Time is exactly same and there is absolutely no delay. So ideally the poller should stop after 10 sec. and not immediately. Also there are 4 files in the directory and its picking up only one.
Please do suggest what's wrong.

Answer 1

Well, I see. The
<int-task:scheduled ref="incomingFiles.adapter" method="stop"
fixed-delay="#{10 * 1000}"/>
produces PeriodicTrigger which result (nextExecutionTime) depends on triggerContext.lastScheduledExecutionTime() and if it is null (your case) it invokes underlying method immidiatelly.
Let's try this!
<task:scheduled ref="incomingFiles.adapter" method="stop"
fixed-delay="#{10 * 1000}" initial-delay="#{10 * 1000}"/>
I mean the same value for the initial-delay to postpone the first stop task for the desired time.
