Description

Job history file is not flushed correctly because isTimerActive flag is not set true when flushTimerTask is scheduled.
It looks like we should set isTimerActive to true when flushTimerTask is scheduled. Otherwise if a new qualified event comes before the current flush timer is expired, flushTimerTask will be canceled and rescheduled.
Also I didn't find any code which set isTimerActive flag to true, So isTimerActive is useless in current code.
