JVM crashes trying to draw very small Arc2D pie fraction when antialiasing
is on. The problem is easily reproducible.

1. Testcase
-----------

import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.geom.Arc2D;
import java.awt.geom.Rectangle2D;
import java.awt.image.BufferedImage;
import java.util.Date;

public class CrashVM {

    public static void main(String[] args) {
       
        BufferedImage image = new BufferedImage(400, 300, BufferedImage.TYPE_INT_RGB);
        Graphics2D g2 = (Graphics2D) image.getGraphics();
        g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                            RenderingHints.VALUE_ANTIALIAS_ON);
        Rectangle2D bounds = new Rectangle2D.Double(168.83125, 54.60624999999999, 162.33749999999998, 162.33749999999998
);
        Arc2D arc = new Arc2D.Double(bounds, 90.0, -4.2154566415320005E-7, Arc2D.PIE);
        System.out.println("About to draw...");
        g2.draw(arc);
        System.out.println("Done --> " + new Date().toString());
    }
}

2. Compile
----------

3. Run
------
