 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);
  }
}
