Description
FULL PRODUCT VERSION :
java version "1.7.0_01"
Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
Java HotSpot(TM) Client VM (build 21.1-b02, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Linux  2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
On Linux, when the TextArea instance is set to non-editable, it does not show a caret when it is focused. This will confuse users. On windows, the focus is visible.

This is reported to java.awt.TextArea .

// I reported http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7119745 , but it was closed, so I update the description and testcase a little and report it again. This problem is definitely NOT swing.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run the testcase with jdk7.
2. Press tab to move the focus to TextArea


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When Focus goes to TextArea, it should be visible.
ACTUAL -
The focus is not visible.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.awt.TextArea;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class OJDK103 {

    public static void main(String[] str) {
        JFrame jf = new JFrame();
        jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JButton jb = new JButton("click");
        JPanel jp = new JPanel();
        jf.setSize(200, 200);
        
        jf.getContentPane().add(jp);
        jp.add(jb);
        
        TextArea ta = new TextArea(6, 10);
        ta.setText("Text Area");
        ta.setEditable(false);
        jp.add(ta);
        
        jf.setVisible(true);
    }
}
