> The logging services project has officially announced the EOL of log4j 1:
> https://blogs.apache.org/foundation/entry/apache_logging_services_project_announces
> In the official binary jetty deployment, we use use log4j 1.2 as our final logging destination, so the admin UI has a log watcher that actually uses log4j and java.util.logging classes. That will need to be extended to add log4j2. I think that might be the largest pain point to this upgrade.
> There is some crossover between log4j2 and slf4j. Figuring out exactly which jars need to be in the lib/ext directory will take some research.
