> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.6.2
> Environment: mac osx capiton/jvm 1.7/log4j-core 2.6.2
> Reporter: yin mingjun
>
> I am migrating my project from log1.x to log2.x, and I was using
> DailyRollingFileAppender before, and now I am trying to use
> RollingFileAppender instead it.
> what i am doing is:
> 1. write a config file, with RollingFile's config, and use
> CronTriggeringPolicy config log file to roll over at middle-night.
> 2. also set it's CronTriggeringPolicy's evaluateOnStartup=true, require check
> roll over at start time.
> 3. I touch my log file to an older time, check it is working alright.
> my touch command is:
> {{touch -t 1607220101 biz-pubsvc-service.log}}
> then i start my project, then I got an InvocationTargetException
> exception...........
> >>>> I then trace into the log4j2's source file, find the exception is caused
> >>>> by CronTriggeringPolicy's initialize method:
> {code}
> public void initialize(RollingFileManager aManager) {
> this.manager = aManager;
> Date nextDate = new Date(this.manager.getFileTime());
> this.nextRollDate =
> this.cronExpression.getNextValidTimeAfter(nextDate);
> if(this.checkOnStartup && this.nextRollDate.getTime() <
> System.currentTimeMillis()) {
> this.rollover(); >>> here, call rollover, need this.future
> }
> this.future =
> this.configuration.getScheduler().scheduleWithCron(this.cronExpression, new
> CronTriggeringPolicy.CronTrigger()); >>> here assign this.future first time
> }
> {code}
> we also refer CronTriggeringPolicy's rollover method's code:
> {code}
> private void rollover() {
>
> this.manager.getPatternProcessor().setPrevFileTime(this.nextRollDate.getTime());
> this.manager.rollover();
> Date fireDate = this.future.getFireTime(); >>> raise null pointer
> exception here !!!
> Calendar cal = Calendar.getInstance();
> cal.setTime(fireDate);
> cal.add(13, -1);
> this.nextRollDate = cal.getTime();
> }
> {code}
> I think this BUG is easy to fix up by moving [ this.future = ...] 's
> assignment just before the call of [ this.rollover(); ].
