PIT : WARNING: Exception on Toolkit thread java.lang.UnsatisfiedLinkError: sun.awt.X11.XlibW

I have a frame to which i have added a button. The whole process i am doing in toolkit thread as follows
 Toolkit.getDefaultToolkit().getSystemEventQueue().invokeAndWait(new Runnable() {
public void run() {
// create a frame & adding the button to it.
}
}

When the frame is visible , i press on the button. I see the following warning.
