I think the behavior is part of BasicTabbedPaneUI.TabbedPaneLayout
unless overridden. Another LAF may or may not rely on it. Ignoring form,
here's how I'd change the function:

/** @author John B. Matthews */
class MyTabbedPane extends JTabbedPane {

public MyTabbedPane() {
this.setUI(new MyTabbedPaneUI());
}

@Override
public String getUIClassID() {
return "MyTabbedPaneUI";
}

@Override
public void updateUI() {
// preclude others
}

private class MyTabbedPaneUI extends BasicTabbedPaneUI {

@Override
protected LayoutManager createLayoutManager() {
return new BasicTabbedPaneUI.TabbedPaneLayout() {

@Override
protected void rotateTabRuns(
int tabPlacement, int selectedRun) {
}

@Override
protected void padSelectedTab(
int tabPlacement, int selectedIndex) {
}
};
}
}
}

Thanks very much for that contribution which I may try to implement.
One thing is clear: I can't have tabs moving all over the place. Too
much operator error confusion in my application, which puts real money
on the line for the trader.

Off-topic is the further issue of the Security Warning (posted
elsewhere) which is another Java "innovation" that kills my app's
reliability, far more serious than this GUI issue. As in the GUI
case, I may abandon using Nimbus; I may also have to abandon upgrading
beyond Java 6 Update 17 as well unless I can find a workaround...
