[jboss-jira] [JBoss JIRA] (WFLY-3695) Distributed web session expiration ScheduledExecutorService leaks threads on undeploy

[Paul Ferraro (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-3695?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Ferraro updated WFLY-3695:
-------------------------------

    Description: The ScheduledExecutorService employed by the SessionExpirationScheduler uses shutdown() to shutdown the thread pool - however, unless we explicitly setExecuteExistingDelayedTasksAfterShutdownPolicy(false), all scheduled tasks will attempt to execute after shutdown!  (was: These thread pools currently shutdown via ExecutorService.shutdownNow() but leave active threads.  Shutdown is also a blocking operation, so Service.stop(...) should be asynchronous.)
