       The java.awt.Toolkit.getFontMetrics(Font f) throws SEGVIOL in
      java full version "JDK-1.2fcs-I" under Solaris 2.6.

      The example:
      --------------------------------8-<---------------------------
      import javax.swing.SwingUtilities;
      import javax.swing.JFrame;
      import java.awt.*;

      class Test {
        public static void main(String[] argv) {
            JFrame f = new JFrame();
            FontMetrics fm = null;
            int result = 0;
            int j,c;

            Font fonts [] = GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();

            if (fonts==null || fonts.length==0)
             System.exit(1);

           for (int ff=0;ff<fonts.length;ff++) { // Try all fonts
            System.out.println(fonts[ff]+"..");
            fm = Toolkit.getDefaultToolkit().getFontMetrics(fonts[ff]);
           }
                 
           f.dispose();
           System.out.println("OKAY");
           System.exit(0);
        }
      }
      --------------------------------8-<---------------------------
