JTable: Pressing F2 on a non-editable cell throws
NullPointerException:

Simple example:

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

public class JTableBugDemo {
    public static void main(String s[]) {
        JFrame frame = new JFrame();

        frame.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
JPanel p = new JPanel();
p.add(new JTable(new AbstractTableModel() {
Object[][] data = {{"1", "2"}, {"3", "4"}};
public boolean isCellEditable(int row, int column) {
return false;
}
public int getRowCount() {
return 2;
}
public int getColumnCount() {
return 2;
}
public Object getValueAt(int row, int column) {
return data[row][column];
}
}));

frame.getContentPane().add(p);
p.setVisible(true);
frame.pack();
        frame.setVisible(true);
    }
}

Run, and press F2 on any cell.
