FULL PRODUCT VERSION :
Java(TM) SE Runtime Environment (build 1.6.0-rc-b93)
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.

use an additional layout, e.g. "us,sk"

This bug is reproducible if sk (or hu, cz) is the only layout set in the system. If you like me have several layouts to switch between, it is not reproducible. 

Now, on this condition a keysym array returned by the system contains not the "NumPad ." which is a convention for the numeric separator but just a comma keysym (0x2c) which is not a numpad key. Once it is not a numpad key, we must use a primary layer keysym to produce a java keycode, which is incidentally 0x7f, delete. At the same time keychar is comma.

Similar behaviour detected in Solaris 10, i586 based on Xorg.

As of now, we are deciding if it is a keypad event just by trying a single keysym in a precisely chosen place in the keysym array. However, certain XKB symbol tables map to this place not a keypad keysym but a regular one (e.g in cz: not a KP_Decimal but just comma). Let's try also a primary-level keysym in the array: if IsKeypadKeysym checks for either of it, declare a given event a keypad event.
