Description

We are upgrading log4j2 from 2.8.2 to 2.19.0 and found this issue:

Archives of log files always contain time from Cron trigger even they were archived by SizeBased trigger

Example:
RollingFile pattern: %d{yyyyMMddHHmm}-%i.gz
Cron expression: 0 0 0 * * ?
Archive: common.log-202212190000-1.gz
Created time: 2022-12-19 12:54
