If I have a class hierarchy (for when despite Josh Bloch's recommendation to "prefer composition 
to inheritance" I go the other way) I will often put in the parent class:

  private final Logger logger = Logger.getLogger(getClass().getName());

This despite the violation of "Don't call an overrideable method during construction."
