/*
JTextPane no longer dispatches keyTyped events

The following code reproduces this problem.
When run under i586/win_nt_4.0 you will see
only the keyPressed and keyReleased events.

Run the same demo under SPARC/Solaris and you
will see keyPressed, keyTyped and keyReleased
for each key you strike.

This showed up under JDK 1.2 RC 1 and worked
fine under JDK 1.2beta4:

import java.awt.*;
import java.awt.event.*;

/**
 * Demonstrates problems with JDK1.2 RC 1--JTextPane no longer
 * dispatches keyTyped events like it used to in JDK1.2beta4. Typing
 * some characters in the pane after startup will show that only
 * keyPressed and keyReleased events are generated...
