Tony Weston updated TOMEE-3801:
-------------------------------
Description:
Hot deploy, with changes to scheduled methods with @schedule, or
programatically using Timer and @timeout , does not update previously deployed
scheduled config.
This is reproducible by using this class:
*package* bug;
{{*import* java.util.Date;}}{{ }}
{{*import* javax.ejb.Schedule;}}
{{*import* javax.ejb.Singleton;}}{{ }}
{{@Singleton }}
{{*public* *class* TestSchedular {}}{{ }}
{{ @Schedule(second = "*/2", minute="*", hour="*" )}}
{{ *public* *void* doIt() {}}
{{ System.*_out_*.println("Fired at "+*new* Date());}}
}
{{}}}
Deploy to tomee. Then update the class with a new timing, say 4 seconds.
compile, and deploy the new war to Tomee. Tomee will continue to use the the
previous 2 second timing after hot-deploy.
Attached file is a video of this happening in Eclipse, as its very easy to
demonstrate, though this bug is absolutely present in a stand alone TomEE
server. The video starts with the schedule set to 2 seconds. After changing
to 4 seconds, and tomee restarting, the scheduled method continues to fire
every 2 seconds.
A work around for this bug is to restart TomEE from scratch after each
deployment. Set bug level to critical since this makes hot deploy very risky
if it is not picking up every change in the deployment. At the very least, a
warning should be put into the logs on hot-deploy, if schedular has been
detected to be in use.
