[jboss-jira] [JBoss JIRA] (WFLY-5863) EE concurency should queue scheduled tasks, instead of failing on timeout

[James Olsen (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-5863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13163410#comment-13163410 ] 

James Olsen commented on WFLY-5863:
-----------------------------------

I think the determination of when the server is 'suspended' is also flawed.  I have a {{@Singleton}} {{@Startup}} EJB with a {{@Resource ManagedScheduledExecutorService managedScheduledExecutorService;}} that starts a scheduled task in the {{@PostConstruct}} method.  During server shutdown I am getting the following error *BEFORE* the completion of the EJB's {{@PreDestroy}} method (which amongst other things cancels the task):

{noformat}ERROR [org.jboss.as.ee] (EE-ManagedScheduledExecutorService-default-Thread-3) WFLYEE0110: Failed to run scheduled task: java.lang.IllegalStateException: WFLYEE0111: Cannot run scheduled task javax.enterprise.concurrent.ManagedExecutors$ManagedRunnable at b16ffc9 as container is suspended

	at org.glassfish.enterprise.concurrent.ManagedThreadFactoryImpl$ManagedThread.run(ManagedThreadFactoryImpl.java:250){noformat}

As I have declared a dependency on the {{ManagedScheduledExecutorService}}, shouldn't it remain useable until the EJB's {{@PreDestroy}} method has completed?

> At the moment if a scheduled task is queued and its execution happens when the server is suspended then the task will fail with an exception. It would be better if this was queued as with EJB timers.
