Here is some simple code to display a JTree in a JScrollPane. If you resize the window vertically small enough to require a vertical
scrollbar you will see that it doesn't add a horizontal scrollbar even though some of the viewport is obscured by the vertical
 scrollbar.

But to be honest what it should really have done is added the width of the scrollbar to the preferred size of the viewport in
 determining the preferred size of the scrollpane. In other words it should have made the scrollpane's preferred size wider. This
is probably very difficult to handle in practice because the preferred size would be dependent on whether the scroll bar is being
 shown which is dependent on the size which is affected by the preferred size.

import com.sun.java.swing.event.*;
import java.awt.*;

public class test extends JFrame implements ScrollPaneConstants
{
    private test() throws Exception
    {
        JScrollPane scrollPane = new JScrollPane( new JTree(),
                                              VERTICAL_SCROLLBAR_AS_NEEDED,
                                              HORIZONTAL_SCROLLBAR_AS_NEEDED );

        getContentPane().add( scrollPane, BorderLayout.EAST );

        setSize( 640, 400 );
    }

    public static void main( String[] args ) throws Exception
    {
        new test().show();
    }
}

When the sum of the minimum size of columns in a JTable
with autoresizing enabled exceed the size of the
viewport (the JTable is contained by a JScrollPane)
a horizonal scrollbar should be added to the JScrollPane.
