The default JDK only log to the console. There is an 
additional line (commented out)
which allows you to use the java.util.logging.FileHandler additionally:
# "handlers" specifies a comma separated list of log Handler
# classes.  These handlers will be installed during VM startup.
# Note that these classes must be on the system classpath.
# By default we only configure a ConsoleHandler, which will only
# show messages at the INFO and above levels.
handlers= java.util.logging.ConsoleHandler

# To also add the FileHandler, use the following line instead.
#handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandler

Also specifiy
java.util.logging.FileHandler.pattern = %h/java%u.log
with the correct path to your logging directory and a better name for it.

If this is a default installation and no other apps are running in it, 
you just have to remove any log4j.jars from
the classpath.
