Description
FULL PRODUCT VERSION :
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux vilma 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:45:36 UTC 2010 x86_64 GNU/Linux


A DESCRIPTION OF THE PROBLEM :
The following java class crashes the VM all times:

import java.awt.geom.*;
import java.awt.*;
import java.awt.image.*;

public class PathDasherSegfault {
    public static void main( String[] args ) {
        GeneralPath path = new GeneralPath(GeneralPath.WIND_NON_ZERO);
        path.moveTo(8408685.0, -1124643.0);
        path.curveTo(8408693.0, -1124638.8, 8408703.0, -1124636.8,
8408712.0, -1124637.0);

        BufferedImage image = new BufferedImage(100, 100,
BufferedImage.TYPE_INT_RGB);
        Graphics2D g2 = image.createGraphics();

        Stroke stroke = new BasicStroke(0.8503937f,
BasicStroke.CAP_BUTT, BasicStroke.JOIN_MITER, 10f, new
float[]{10.204724f,
                5.102362f}, 0f);
        g2.setStroke(stroke);

        System.out.println("about to draw");
        g2.draw(path);
        System.out.println("OK");
    }

}

stack trace is the following:
