A DESCRIPTION OF THE PROBLEM :
The CTRL+number shortcuts do not work properly (the top row of the alphanumeric part of the keyboard. Instead of CTRL+1 the jdk recognises CTRL+PLUS and the other CTRL+2 .. CTRL+0 shortcuts are not recognised. This happens with the sk keyboard and cz keyboard, not with the hu keyboard. In the sk and cz layouts the top row of the alphanumerical keys is +, l caron, s caron, c caron, t caron, z caron, y acute, a acute, i acute and e acute, respectively, the numbers are produced by using SHIFT and these keys. Adding SHIFT to the combinations will give CTRL + SHIFT + PLUS instead of CTRL + SHIFT + 1, for instance.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
open a swing based app, where one can set the shortcuts, jEdit, for instance. Edit the shortcuts in the appearing window.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
CTRL + 1 should give CTRL+1, CTRL+2 should give CTRL+2, etc.
ACTUAL -
CTRL+1 gives CTRL+PLUS, CTRL+2 gives nothing, CTRL+3 gives nothing either, etc.

REPRODUCIBILITY :
This bug can be reproduced always.
