JCK test JCK-runtime-6a/tests/api/java_awt/Component/index.html testPaintAll fails on linux
Here is the output: http://moonblade.russia.sun.com/set/java/jck/qa-results/jdk_results/jdk7/b16/JCK6a/runtime-SUSE10-x86-client-Xint-Xconcgc-Xbatch-Xdebug/workDir/api/java_awt/Component/index.jtr

A standalone test is written and it seem reproduces the problem on Ubuntu Linux with GNOME.
import java.awt.*;
import javax.swing.*;
import java.awt.image.BufferedImage;

public class TestPaintAll {

    public static void main(String [] args) throws Exception {

            Component lwComponentStub;
            Button hwComponentStub;
            Frame frame;

                lwComponentStub = new Component(){
public void paint(Graphics g) {
System.out.println("LW paint() call");
                        }
};

                hwComponentStub = new Button(){
public void paint(Graphics g) {
System.out.println("HW paint() call");
                        }
};
                BufferedImage graphicsProducer =
                    new BufferedImage(BufferedImage.TYPE_INT_ARGB,1,1);
            
                Graphics g = graphicsProducer.getGraphics();
                

                frame = new Frame();
                frame.setLayout(new GridLayout());
                frame.add(lwComponentStub);
                frame.add(hwComponentStub);
                frame.setSize(new Dimension(50,50));
                frame.setVisible(true);

System.out.println("1-------------------");
Thread.sleep(3000);
System.out.println("2-------------------");

                frame.paintAll(g);
               //frame.paintAll(frame.getGraphics());
    }
}

On Linux it prints:
1-------------------
LW paint() call
LW paint() call
HW paint() call
2-------------------

On Windows it prints:
1-------------------
LW paint() call
HW paint() call
2-------------------
LW paint() call
HW paint() call

On Linux with Motif enabled it prints:
1-------------------
LW paint() call
LW paint() call
HW paint() call
2-------------------
LW paint() call
HW paint() call
