Java Swing vomits font information to std out

I have a Java program that I have written in Eclipse running in jdk1.8.0_73 on Ubuntu 14.04

public class Vomit {
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        JLabel label = new JLabel();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Font font = new Font("Helvetica", 72, Font.BOLD);
        label.setFont(font);
        label.setText("Vomit!!");
        frame.add(label);
        frame.pack();
        frame.setVisible(true);
    }
}

Without any expiation, the frame is created at the minimum size and no text is displayed in the frame. Even stranger, my console output gets filled with a ton of font information.

Here is an example of a small segment of the output:

Font 244 Pattern has 17 elts (size 17)
    family: "URW Palladio L"(w)
    style: "Italic"(w)
    slant: 100(i)(w)

    postscriptname: "URWPalladioL-Ital"(w)

There are many more of these. When I pipe std out to a file there are almost 40,000 lines of this nonsense.

The exact same thing sometimes happens when I launch "xscreensaver-demo". Is this a problem with Java Swing (I don't even know that xscreensaver-demo uses Swing)? What is going on here?

For the JFrame showing it at minimum size, you have this line wrong:

Font font = new Font("Helvetica", 72, Font.BOLD);

Should be:

Font font = new Font("Helvetica", Font.BOLD, 72);
