keyboard tests failed on Vista for Arabic locale throwing StringIndexOutOfBoundsException

Build: b77
platform: Windows Vista CTP build 5308
Locale : ar
GS testsuite used: GS-Tonga_10.zip


1)Executed the tests for arabic locale from this testsuite using the keywords ar&&!manual
2)you will notice the following testcases have failed :
keyboard/windows_Swing_Keyboard_ar
keyboard/windows_AWT_Keyboard_ar

NOTE:
-I have attached the Arabic.png files from logs files separately as awt-Arabic.png and
swing-Arabic.png files for easy reference to below details.
-Windows.log files are attached separately for AWT & SWING.


PROBLEMS:

1) multiple inputs of the same key i.e Windows V-Keycode found & the J-keycode for them are showing different. Mismatch is resulting from this.
i.e
  awt-Arabic.png : notice repeatitions for VK_S, VK_T,VK_U
  swing-Arabic.png : you will find repeatitions for VK_A,VK_B
Observations:
- N-Char is same but the J-Keycode is different for these repeated ones
i.e swing-Arabic.png : Though VK_A is repeated the N-Char is same,but the J-Keycode is different
- J-Char is returned based on this J-Keycode(which is incorrect for repeated entries). Hence J-Char mismatching with N-Char & resulting in failure

Need to investigate 2 things here:
- why repeatetions are found with Windows V-Keycodes
- why the J-Keycodes for the same Windows V-Keycodes are different

Filing it as JDK bug since the J-Keycode is the result of getKeyCode() in testcase & its different for same key input.
But Not sure of the reason for repeatitions.


2)StringIndexOutOfBoundsException found in logs :

[today I could not cross-check with Non-Vista windows.I will update the results after more investigation on that if any.]
