A DESCRIPTION OF THE PROBLEM :
This is to reopen the never fixed, and yet closed bug 4262044.

I have just spend a days work on discovering why KeyEvent.getKeyCode() never returns KeyEvent.VK_PLUS or KeyEvent.VK_MINUS and several others, to finally after a series of fruitless experiments to "Google web" for the issue, and to discover bug 4262044 filed 1999, closed without a fix in all these years!

This is very unsettling. Please be so nice to accept that I am unable to understand what is the problem, to understand the quite convoluted wording of the evaluation of the bug 4262044.

Which key has than the key code == VK_PLUS, if not the "+/=" or the keypad "+"?

What value have the VK-codes than , if they are wrong, at least some of them are wrong?

What is than the VK_nnn code for "=/+" of they keypad "+"?


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use the code from bug 4262044, still the same problem shows up.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
At least the keypad "+" key pressed should cause KeyEvent with KeyCode=VK__PLUS.
ACTUAL -
Node of the keys delivers VK_PLUS, VK_MINUS, VK_EQUALS, to name a few. I do not even known how many of the VK_nnn codes are wrong alongside of these codes.

REPRODUCIBILITY :
This bug can be reproduced always.
