Sample testcase code :

import java.awt.event.*;
import java.util.*;

public class BugWithDnDSwing extends JFrame {

JPanel panel;

private JTextField tfSource;
private JTextField tfDest;

private JList listSource;
private JList listDest;

public BugWithDnDSwing() {
super("BugWithDnDSwing");
setSize(400,400);
panel = new JPanel();
panel.setLayout( null );

tfDest = new JTextField();
tfDest.setBounds(150,40,100,20);
panel.add(tfDest);

String[] data = {"one", "two", "three", "four"};
listSource = new JList(data);
listSource.setBounds(10,40,100,60);
listSource.setDragEnabled(true);
panel.add(listSource);

panel.setVisible(true);
getContentPane().add(panel);
setVisible(true);

addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent ae) {
System.exit(0);
}
});
}

public static void main(String[] args) {
new BugWithDnDSwing();
}
}

To reproduce :

1) Compile the above code and execute it.
2) Press LEFT mouse button on a non-selected item of JList.
3) Start dragging without releasing the mouse button.

You will see that nothing gets dragged.

NOTE : This is reproducible on all platforms.
