[jboss-jira] [JBoss JIRA] (WFLY-4330) Async service with EJB pool blocks threads not used

[Bartosz Baranowski (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-4330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13086685#comment-13086685 ] 

Bartosz Baranowski commented on WFLY-4330:
------------------------------------------

Ach, got it. In such case this should probably be filed as feature to be able to provide async thread pools. ATM there is only global thread pool for all async calls.

> I've created a bean pool to limit the number of some instances. In that case maximum 5 instances.
> <pools>
> 	<bean-instance-pools>
> 		<strict-max-pool name="slsb-max5" max-pool-size="5" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>
> 		...
> 	</bean-instance-pools>
> </pools>
> The idea was to have some async service that work simultaneous.
> @Stateless
> @Pool("slsb-max5")
> public class AsyncService {
>     @Asynchronous
>     public Future<LocalDateTime> async2Seconds() {
>         //some parallel work...
>     }
> }
> The problem is when I invoke simultaneous more than 5 times it blocks the threads even it is not using (async thread-pool-name="default", default=10)
> Attached an example project (configure slsb-max5 pool and access /test-thread-pool/rest/async-resource)
