- Use System locale and time zone for default date/time format,
        so it matches the wrapper log time (we can't set the wrapper log time zone).
        (existing installs must remove logger.dateFormat line
         in logger.config to get system default format)
      - Force RuntimeExceptions to CRIT level
      - Don't have log() count buffer size
