Create a table with Integer.MAX_VALUE rows (2147483647). Display
it. Only the first 126322567 rows are displayed. Here is a sample
program:

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

final class Main
    extends JFrame
{

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

Main()
{
    getContentPane().setLayout(new BorderLayout());

    AbstractTableModel dataModel =
	new AbstractTableModel() {

	public Class getColumnClass(int columnIndex)
	    {
		return String.class;
	    }

	public int getColumnCount()
	    {
		return 1;
	    }

	public String getColumnName(int columnIndex)
	    {
		return "Row Number";
	    }

	public int getRowCount()
	    {
		return Integer.MAX_VALUE;
	    }

	public Object getValueAt(int rowIndex, int columnIndex)
	    {
		return Integer.toString(rowIndex + 1);
	    }

	public void setValueAt(Object aValue, int rowIndex, int columnIndex)
	    {
	    }

	public boolean isCellEditable(int rowIndex, int columnIndex)
	    {
		return false;
	    }

    };

    // Create the JTable

    System.out.println("Creating table with " +
		       dataModel.getRowCount() + " rows");
    System.out.println();
    JTable table = new JTable(dataModel);

    TableColumnModel columnModel = table.getColumnModel();
    int columnCount = columnModel.getColumnCount();
    for (int i = 0; i < columnCount; i++) {

	TableColumn column = columnModel.getColumn(0);

	column.setHeaderValue("Row Number");
	column.setCellRenderer(new DefaultTableCellRenderer());
	column.setResizable(true);
	column.setMinWidth(200);
    }
    table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

    JScrollPane scrollpane = new JScrollPane(table);
    getContentPane().add(scrollpane);

    // Display the window

    pack();
    setVisible(true);
}

}

======================================================================
In addition to this, it is possible to use this same sample program to make the table barf up exceptions.  Here's how:

1. Launch the sample
2. Scroll to row 120 million or so
3. Try to click in a cell

it will throw and OutOfMemeoryError from Bitset.ensureCapcity.  This is called indirectly from DefaultListSelectionModel.changeSelection().
