1) Bugreport.txt described the detailed problem, required locale setting for OS
   requried japanese fonts rpm, instruction to reproducing testcase.
  
2) KeyboardTest.java is java testcase code

kinput2 as input method frontend
cannaserver as conversion backend

processes:

wnn 1198 1 0 Oct19 ? 00:00:00 /usr/sbin/cannaserver -u wnn -r /var/lib/canna
d024679 11682 11680 0 10:36 pts/9 00:00:00 kinput2 -canna

Description:
============

After activating the input method on an entry field with Ctrl-SPACE
and entering and commiting text, a focus change to another entery
field in the same frame deactivates the input method. Under 1.4.2 the
input methods state indicator is not correctly updated, under 1.5.0_01
the indicator goes off. To further type text into the second field the
input method has to be activated again, preventing fluent data entry.

Reproduction:
=============

JRE 1.4.2

Install the necessary fonts from xtt-fonts-xxx.rpm setup the required
japanese locale, cannaserver and kinput2

start the test program : java IMTest.FontTest

Click into the first entry field, activate the input method with
Ctrl-SPACE. Note the IM indicator showing the active script. Enter ka
and commit the text.

Press TAB to focus the second entry field. Note IM indicator still
indicates the IM is active.

Enter ka and note that input is not sent to the IM frontend.

Press Ctrl-SPACE and note that the IM indicator does not change.

Enter ka and note the IM is active again.
