Logging Ad Nauseum

I guess I have to mention logging in one way or the other this week. A lot of good stuff has been written and communicated about this. All I want to say is that you should follow the advice to always use the latest recommended versions of your dependencies. Another piece of advice I will throw in is that you should always consider whether you actually need that particular dependency you just added. Take logging, for example. I have always been happy with Java Util Logging (JUL). It is provided for me by the platform, and provides the functionality I have needed.

package dukes;

import java.util.logging.Logger;

class DukeLogs {

    public static final Logger LOGGER = Logger.getLogger("dukes");

    void doStuff() {
        LOGGER.info(() -> "Duke says hello");


This may not be the case for everyone. Log4j provides a lot of useful stuff that you may benefit from in your particular use case. But if you choose to rely on third-party dependencies, always make sure that you follow the recommendations to which version to use (usually the latest)!

See Eclipse and log4j2 vulnerability (CVE-2021-44228) to see the status of the various projects at Eclipse Foundation. Please help keep this list up-to-date for the projects you are involved in!
