Operating Systems:
Linux:
RedHat 7.2 Japanese for IA32 + kinput2 + FreeWnn
SuSE7.1(x86) + kinput2 + FreeWnn
RedHat6.2(x86) + kinput2 + FreeWnn

JDK versions:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-rc-b90)
Java HotSpot(TM) Client VM (build 1.4.0-rc-b90, mixed mode)

Environment setup:
1. Login and start kterm.
2. Kill process of kinput2 for canna as follows.
"ps -ef |grep kinput2"
Then "<canna PID> kinput2 -xim -kinput -canna &" is displayed.
"kill -9 <canna PID>"
3. Start kinput2 for Freewnn as follows.
"kinput2 -xim -kinput -wnn &"
4. Confirm the running of jserver as follows.
"ps -ef |grep jserver"
Then "<jserver PID> /usr/bin/jserver" is displayed.
5. Confirm the Japanese input normally as follows.
Press "Shift+Space"
Then IM status window appears at the lower left of the kterm.
Input "A", then Japanese "A" is input.
Press "Ctrl+J" twice, then candidate selection window appears at the lower left of the kterm.

Steps to reproduce problem:
6. "java JTextTest"
Then JTextArea window appears.
7. Activate IM of Freewnn.
Press "Shift+Space"
Then IM status window appears at the lower left of the JTextArea window.
8. Press Enter on numeric keypad twice.
Then "javax.swing.text.StateInvariantError" appears in the kterm (see below).

JTextTest.java:
import java.awt.*;
import javax.swing.*;
public class JTextTest extends JFrame {
public JTextTest() {
super("JTextArea");
getContentPane().add(new JTextArea());
setSize(300, 300);
show();
}
public static void main(String[] args) {
new JTextTest();
}
}

The problem only happens with FreeWnn (not Canna) and has only been recreated with a Japanese keyboard.
