PreferencesTabBar does not look unified in Mac OS X 10.5/6 running with Java 6 or using JDialog

[GoogleCodeExporter]

What steps will reproduce the problem?
final PreferencesTabBar tabBar = new PreferencesTabBar();
tabBar.addTab("General",null,null);
tabBar.addTab("Proofing",null,null);
tabBar.addTab("Saving",null,null);
final JComponent tabBarCom = tabBar.getComponent();

1. For JFrame:
final JFrame mainFrm = new JFrame();
tabBar.installWindowDraggerOnWindow(mainFrm);
MacUtils.makeWindowLeopardStyle(mainFrm.getRootPane());
mainFrm.getContentPane().add(tabBarCom);

2. For JDialog:
final JDialog mainDlg = new JDialog();
tabBar.installWindowDraggerOnWindow(mainDlg);
MacUtils.makeWindowLeopardStyle(mainDlg.getRootPane());
mainDlg.getContentPane().add(tabBarCom);
