Java log4j logger doesn't create log files – Telegram API

I wrote little telegram bot based on java. Also i connected logger (log4j library) for log bot activity.

After server restart cron execute bot jar-file automatically with this command:

@reboot sleep 5 && java -jar /var/blablabla/praetorian19-1.0-jar-with-dependencies.jar

In this case logger doesn’t create any log files.

But, if i start bot directly under root with the same command, all work well. I see new log files and they updating correctly.

Directory and bot file have a 777 rules recursively.

Is any idea in which side i must dig?
