When scheduling a new Timer, the engine first checks to see if that timer job already exists. It does this by calling getTimerByName on the EJBTimerScheduler

public TimerJobInstance getTimerByName(String jobName) {
for (Timer timer : timerService.getTimers()) {
Serializable info = timer.getInfo();
if (info instanceof EjbTimerJob) {
EjbTimerJob job = (EjbTimerJob) info;
EjbGlobalJobHandle handle = (EjbGlobalJobHandle) job.getTimerJobInstance().getJobHandle();
if (handle.getUuid().equals(jobName)) {
logger.debug("Job {} does match timer and is going to be returned", jobName);
return handle.getTimerJobInstance();
}
}
}
return null;
}

Unfortunately, it appears that WebSphere is lazy-loading the TimerInfo objects, and only retrieves them from the database when the timer.getInfo is called on each timer. This leaves a window between when the list of timers is retrieved and when the timerInfo is retrieved where the timer may have fired and been removed from the database.

Since we don't care about timers that are no longer present, is it possible to put a guard in here against the exception which is thrown? (stacktrace below)
