Backspace key doesn't work neither in TextField nor in JTextField

[Alex Pivovarov]

jdk-1.5.0p2_5
FreeBSD 6.1-Prerrelease #1

Problem:
Backspace key doesn't work neither in TextField nor in JTextField .
And other service keys like Tab, Del, Space also don't work in AWT or
SWING applications.

But if I use linux-sun-jdk1.5.0.06,2 - these keys work fine.
