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. A good time to start using the new standard System.Logger API introduced in Java 9: https://t.co/SaBUnqEZqF. It works like SLF4J and by default logs using JUL but can use Log4J or any othet logging under the hood.
