      Previous versions of JBoss EAP 5 carried a bug that, when encountered, resulted in unnecessary DEBUG messages and CPU usage. The bug presented when an EJB timer was canceled. The timer was removed from the persistence store and ceased invoking the EJB Timeout, however a TimerTaskImpl would be left in the thread pool that would continue to poll the state of the canceled timer and log DEBUG messages. This issue has been resolved in this release.

    Description

      When a EJB timer is cancelled, it no longer invokes the EJB Timeout and it is removed from the persistence store, however there is a TimerTaskImpl left in the Thread Pool, and it will continue to run and check the state (which is cancelled) and log debug messages. These should be removed as they are wasting CPU cycles.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
