It simply sounds like a bug to me. The behavior should not be different.

Hi all,
I found TextArea's/TextField's enableInputMethods is not working on
linux,
even enableInputMethods(false) is invocated, the input method can still be
enabled. The testcase is as follows:
/*
* ImfAWTTest.java
*/
import java.awt.Component;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Frame;
import java.awt.TextArea;
import java.awt.TextField;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JTextArea;
import javax.swing.JTextField;
public class ImfAWTTest extends Frame {
Component c;
public ImfAWTTest() {
super("Single Frame --- AWT Frame");
// set layout here.
setLayout(new FlowLayout());
// add components here.
c = new TextArea("TextArea component(No IM)");
c.enableInputMethods(false);
c.setPreferredSize(new Dimension(400, 100));
add(c);
c = new JTextArea("JTextArea component");
c.enableInputMethods(true);
c.setPreferredSize(new Dimension(400, 100));
add(c);
c = new TextField("TextField component(No IM)",52);
c.enableInputMethods(false);
add(c);
c = new JTextField("JTextField component(No IM)");
c.enableInputMethods(false);
c.setPreferredSize(new Dimension(400, 20));
add(c);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent event) {
System.exit(0);
}
});
setSize(850, 360);
setVisible(true);
}
public static void main(String[] args) {
new ImfAWTTest();
}
}
Reproduce steps are:
1. On linux system, run the testcase with b143.
2. Click 'TextArea component(No IM)'.
3. Switch Ime window, and type some characters into it
Expectation:
IME cannot be enabled.
Result:
IME can be used to input.
Investigation:
This behavior was developed when Java was using Motif library,
however Java7's
TextArea/TexField does not use Motif any more, so enableInputMethods doesn't
work.
I suppose we need to update the specification about the behavior.
Any comments?
