[jboss-jira] [JBoss JIRA] (WFLY-3430) Recurring Timers are called concurrently

[Stuart Douglas (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-3430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12978141#comment-12978141 ] 

Stuart Douglas commented on WFLY-3430:
--------------------------------------

I think that @Schedule timers should not be executed concurrently either, otherwise there is the very real possibility of having multiple jobs for the same timer running constantly, if the job is taking longer than the schedule expiration time. If a user does want them to execute concurrently there is a very simple way to achieve this, namely have the timer execute an async EJB method, or use the new EE concurrency executors.

> That is not the case. I don't think the current behavior is actually expected.
