The following program opens a JFrame with a JToolBar and two JButtons on it.
The separator between the buttons draws an ugly line with Windows L&F (only).
The first button can be used to change the L&F to verify that.

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class ToolBarFrame extends JFrame {

    public ToolBarFrame() {
      JToolBar toolBar = new JToolBar();
      JButton button = new JButton("change L&F");
      getContentPane().setLayout(new BorderLayout());
      getContentPane().add(toolBar, BorderLayout.NORTH);
      toolBar.add(button);
      toolBar.addSeparator();
      toolBar.add(new JButton("foo"));
      button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String lfName = null;
if (UIManager.getLookAndFeel().getClass().getName().equals
("com.sun.java.swing.plaf.motif.MotifLookAndFeel")) {
lfName = "javax.swing.plaf.metal.MetalLookAndFeel";
} else if (UIManager.getLookAndFeel().getClass().getName().equals
("javax.swing.plaf.metal.MetalLookAndFeel")) {
lfName = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
} else {
lfName = "com.sun.java.swing.plaf.motif.MotifLookAndFeel";
}
try {
UIManager.setLookAndFeel(lfName);
} catch (Exception ex) {
ex.printStackTrace();
}
SwingUtilities.updateComponentTreeUI(ToolBarFrame.this);
ToolBarFrame.this.pack();
}
      });
    }

    public static void main(String[] args) {
      try {
UIManager.setLookAndFeel
("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
      } catch (Exception ex) {

      }
      ToolBarFrame frame = new ToolBarFrame();
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.pack();
      frame.setVisible(true);
    }
