PrintWriter-based logging utility for classes too low level to use org.apache.logging.log4j.status.StatusLogger. Such classes cannot use StatusLogger as StatusLogger or org.apache.logging.log4j.simple.SimpleLogger depends on them for initialization. Other framework classes should stick to using StatusLogger.
