title: Do you find java.util.logging sufficient?
body: <p>Per the title, do you find the default Java logging framework sufficient for your needs?</p>
  
  <p>Do you use alternative logging services such as <a href="http://logging.apache.org/log4j/" rel="noreferrer">log4j</a> or others? If so, why?
  I'd like to hear any advice you have regarding logging requirements in different types of projects, and when integrating frameworks is actually necessary and/or useful.</p>
