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.
