I'm confused about how to control logging levels.  I'd expect this code:

import java.util.logging.Logger;
import java.util.logging.Level;
public class LoggerTest {
    private static Logger log =
Logger.getLogger(LoggerTest.class.getName());
    public static void main(String [] args) {
        log.setLevel(Level.ALL);
        log.severe("severe message");
        log.warning("warning message");
        log.info("info message");
        log.fine("fine message");
        log.finer("finer message");
        log.finest("finest message");
    }
}

to print all six log.* messages to the console, but instead I get the
default behavior of only printing severe, warning and info.

Where have I gone astray?

Thanks.
