Description Jan Andres 2010-03-28 09:21:42 UTC

Description of problem:

I have configured FC12 to use ibus and anthy for Japanese language input.
When I run any Java application (e.g. jconsole), after the application
window first opens, I can enter Japanese text just fine: After pressing
Ctrl-Space, the ibus toolbar will pop up in the lower right part of the
screen, and after entering some characters and pressing the space bar
twice, the "box" with suggested Kanji completions will show up.

Now, after I focus another window and then come back to the Java application,
pressing Ctrl-Space will still activate the Kanji input mode and the
keyboard works as expected, but neither the ibus toolbar nor the
Kanji completions window show up any more. Clicking the ibus icon in
the system tray brings up the message, "No input window".

This problem is observed with any version of Java including the Fedora-
provided java-1.6.0-openjdk as well as Sun's own 1.6.0_18 version (both
32 and 64-bit versions). It is not observed in any non-Java applications.



Version-Release number of selected component (if applicable):

anthy-9100h-10.fc12.x86_64
ibus-1.2.1-1.fc12.x86_64
ibus-anthy-1.2.0.20100115-1.fc12.x86_64
ibus-gtk-1.2.1-1.fc12.x86_64
ibus-libs-1.2.1-1.fc12.x86_64
ibus-table-1.2.0.20100111-1.fc12.noarch
java-1.6.0-openjdk-1.6.0.0-36.b17.fc12.x86_64
java-1.6.0-openjdk-demo-1.6.0.0-36.b17.fc12.x86_64
java-1.6.0-openjdk-devel-1.6.0.0-36.b17.fc12.x86_64
java-1.6.0-openjdk-plugin-1.6.0.0-36.b17.fc12.x86_64


Steps to Reproduce:
1. Enable ibus via IM Chooser and configure it to use "Japanese - Anthy"
   input method.
2. Run jconsole from java-1.6.0-openjdk
3. Activate any text input field in the jconsole GUI, press Ctrl-Space.
   ibus toolbar will show up. Press Ctrl-Space again to switch back to
   "regular" input.
4. Focus another window, then come back to jconsole window.
5. Again press Ctrl-Space in any text input field. ibus toolbar will
   no more show up.

This is a bug in java. It does not set focus correctly. It will be fixed in next java update release around May, 2010.

Comment 2 Jan Andres 2010-05-17 16:11:24 UTC

Now, I'm not sure what was done to address this issue, but after my latest
"yum update" run, I can no more reproduce this problem -- even when
using Sun's JDK 1.6.0_18, the version in which I had certainly observed
the problem at the time it was reported. It looks to me like some kind of
fix/workaround was implemented outside of Java.

So, from my perspective, the bug can be closed.

Comment 3 Peng Huang 2010-05-18 01:57:33 UTC

Yeah. I added some workaround code in ibus for this.

Comment 4 Jan Andres 2010-05-19 17:43:26 UTC

All right, thanks for caring.
