Please handle logging levels, control of logging levels by package, log file rotation and logging to stdout instead or in addition to a file. Also, log statements should contain the calling class and method. Please also make sure that your logging implementation can be used by any libraries that you reference, I'd like to have their logs in the same format as the application logs and be able to control their level as well. Do you still want to build something from scratch and maintain it yourself? Or would you rather not waste weeks of your time reinventing something that already exists and that other developers are already familiar with?
