APAR status
Closed as program error.
Error description
When we create IntervalTimer by calling TimerService.createIntervalTimer, the handleTimeout of the timer is executed periodically. And we expect that the current scheduled timer can be cancelled by calling timerService.getTimers and the following Timer.cancel method. But even after we call the cancel for the timer, the scheduled timer executes its handleTimeout if we select "Share thread pool configured for persistent timers" of "EJB timer service settings".
Local fix
uncheck "Share thread pool configured for persistent timers"
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server with non-persistent EJB timer * * applications * **************************************************************** * PROBLEM DESCRIPTION: Non-persistent interval EJB timers may * * expire and run one timer after being * * cancelled * **************************************************************** * RECOMMENDATION: * **************************************************************** After a non-persistent interval EJB timer expires and runs at least one time, then any attempt to cancel the timer will result in the timer still expiring and running one more time at the next scheduled interval after the cancel has completed.
Problem conclusion
The EJB container has been updated to ensure non-persistent interval EJB timers will not expire and run again after being cancelled. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.12.
