问题
When I trying to use default keymaps like Ctrl-C, Ctrl-V, etc. they not working.
When I trying to map custom keymap, I get error by pressing on character keys:
Unknown keyCode: 0x0
What it can be? I tried to install Java 1.6, 1.7, same thing.
PS: Using Fedora 19
EDIT
My default lang is English. But playing with keyboard settings of XFCE made it work oO. Issue with keyboard layouts.. Thanks

What's your primary keyboard layout. Make sure it's English and not Russian.
Try adding
-Dide.non.english.keyboard.layout.fix=trueinto youridea.propertiesfile.

Changing the main keyboard layout from XFCE settings to English(Macintosh) worked for me! (after long struggle)
You might need to play with the keyboard layout variant to match your physical keyboard
Tested with Oracle Java 1.7 on Debian 64bit (Jessie)

As a temporary workaround:
Copy from here https://github.com/zheludkovm/LinuxJavaFixes two files:
LinuxJavaFixes-1.0.0-SNAPSHOT.jar
javassist-3.12.1.GA.jar
Add the following line to JVM options:
-javaagent:[path to directory with jar files]/LinuxJavaFixes-1.0.0-SNAPSHOT.jar
For example, you can add this lines to ~/.profile
_JAVA_OPTIONS="-javaagent:[path to directory with jar files]/LinuxJavaFixes-1.0.0-SNAPSHOT.jar"
export _JAVA_OPTIONS
Thanks zheludkovm and Sergey Komarov
