> Key: EJBTHREE-1330
> URL: https://issues.jboss.org/browse/EJBTHREE-1330
> Project: EJB 3.0
> Issue Type: Bug
> Components: timerservice-mk2
> Affects Versions: AS 4.2.2.GA, AS 5.0.0.Beta4
> Reporter: Galder Zamarreño
> Assignee: Carlo de Wolf
> Priority: Minor
>
> The default EJB timer service used by the EJB3 layer is based on
> org.jboss.ejb3.timerservice.jboss.JBossTimerServiceFactory which delegates
> to the standard org.jboss.ejb.txtimer.EJBTimerService.
> For EJB3 beans using the EJB timer service the thread local pool should not be used.
> Since the current EJB timer service creates a new thread for each timer being created, the
> thread local pool will create a matching instance of the bean for that thread. Thus the number
> of active instances in total can effectively grow unchecked and thus an OOM will occur.
