When a text component loses focus while composing, VM hangs.
Run the following code, click one of the two text components, invoke Input Method, type ji, which will be composed to a Japanese kana, click the other component. VM hangs.
Note calling to endComposition in focuse listener does not help.
Test environment:
OS: Redhat Linux 6.2J
IME: Canna w/ Input2

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
