Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)


The registerKeyboardAction() method was NOT deprecated in 1.3, but you
implemented workarounds that crash.ActionStandin should not crash.

This code works in 1.2.2 when you press CTRL-A, nothing happens.
in 1.3.0 it Crashes with a NPE

  To reproduce the problem modify
jdk1.3/demo/jfc/TableExample/src/TableExample4.java

Add the appropriate imports:
import javax.swing.event.*;
import java.awt.event.*;

Add registerKeyboardAction() after JTable creation:
// Create the table
JTable tableView = new JTable(dataModel);

// unregister ctrl-A
tableView.registerKeyboardAction(null, KeyStroke.getKeyStroke(KeyEvent.V
K_A, ActionEvent.CTRL_MASK), JComponent.WHEN_FOCUSED);

Compile and run. Press <CTRL>A. The app crashes in 1.3 it does not in 1.2.2.
