It is no longer possible to serialize awt Font objects. This is because
the Font class now has a FontObject field, and some FontObjects such as
sun.java2d.T1FontObject aren't serializable.

If you try and run the test program below you get:

Font write failed: java.io.NotSerializableException: sun.java2d.T1FontObject
java.io.NotSerializableException: sun.java2d.T1FontObject
        at java.io.ObjectOutputStream.outputObject(ObjectOutputStream.java:753)

public class Test extends java.awt.Frame {

    public static void main(String argv[]) {
        Frame frame = new Test();

        frame.setBounds(200,200,200,200);
        frame.show();

        Font font = frame.getFont();

        try {
            java.io.FileOutputStream fout = new java.io.FileOutputStream("foo.ser");
            java.io.ObjectOutput s = new java.io.ObjectOutputStream(fout);
            s.writeObject(font);
            s.close();

            System.exit(0);

        } catch (Exception ex) {
            System.err.println("Font write failed: " + ex);
            ex.printStackTrace();
        }
    }
