This problem is similar to 4432056 but it's a little bit different.

Reproduce:
   - Execute the attached program as follow.
     % cd awt/classes
     % java awttest -command aaaaaaaaaaaa
   - Click on the place before the 2nd character from the last
     of "a" currently displayed on JTextArea.
   - Enter the following characters in Conversion mode.
     "nihonngonyuuryokukaisi"
   - Convert it to press a space bar.
   - Enter an End key to move a caret to the end of the string.
   - Enter some characters to make a preedit string.

You can see the problem that no preedit string is displayed.
This behavior is different from the case on a native Motif sample.
