December was not a good time for Java developers and even less for Ops. The former had to repackage their apps with a fixed Log4J’s version, and the latter had to redeploy them - several times. Yet, every cloud has a silver lining. In my case, I learned about System.Logger. There was a 'Moved Permanently' error fetching URL: 'https://twitter.com/OndroMih/status/1469599938782932992' In short, System.Logger is a façade over your logging engine.
