On RHEL-5 under the C locale, the caps lock key does not work correctly in a TextArea. The issue appears to be similar to a very old bug: 4080004.

Reproduction instructions:
Reproduction instructions:

1. Under the C locale, launch our testcase with MToolkit.
  $ java TextAreaTest

2. Move the input focus to the TextArea window and enter some characters. Lower case characters are displayed in the TextArea.

3. Press Caps Lock key.

4. Input some characters. Lower case characters are displayed in the TextArea. Expected result: upper case characters should be displayed.
