Java HotSpot(TM) Client VM (build 1.6.0-rc-b93, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux bartkoz 2.6.13-15.10-default #1 Fri May 12 16:27:12 UTC 2006 i686 i686 i386 GNU/Linux


EXTRA RELEVANT SYSTEM CONFIGURATION :
sk, hu, cz keyboard layouts

A DESCRIPTION OF THE PROBLEM :
The decimal separator of the numerical keypad does not work as expected. When entering asdfghjkl in a swing app (tested on jEdit, ArgoUML and others) and then typing 0,1 with the numerical keypad gives asdfg0,1jkl instead of asdfg0,1hjkl. Experienced with sk, hu, cz keyboard layouts (but not pl, for example)


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. switch the keyboard layout to sk:
  setxkbmap -model pc105 -layout sk
2. open a swing app, e.g. jEdit
3. type asdfghjkl
4. move the cursor to 'g'
5. type 0,1 with the numerical keyboard

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
asdfg0,1hjkl
ACTUAL -
asdfg0,1jkl

REPRODUCIBILITY :
This bug can be reproduced always.
