The em of Ja Hiragana can't be selected from the choicebox by the keyboard input

    Details

      Description

       (1) Working environments
       OS : Solaris2.6, Windows NT4.0/95
       JDK : JDK1.1.8, JDK1.2 fcs
       Window : CDE
       Japanese Input : Atok7, Atok8
       
       (2) Symtom
       Step1: Read a html file ComboSelect.html including the applet.
               (You can also access http://speed.japan/~kyo/ComboSelect.html
                to see the symtom. The Java plugin1.2 is needed.)
       Step2: Focus the ChoiceBox.
       Step3: You can select both alphabet and Japanese Hiragana items
               in the box by mouse or by arrow-keys.
               However, you may find the em of Japanese Hiragana can't be
               selected by the keyboard input directly, although the alphabet
               items can be.
               
      Notice: If you run the testcase as an application type
              on IBM VisualAge for Java 2.0,
              there is no problem to select the em of Japanese Hiragana
              by the keyboard input directly.

      We find the slection by key-board is related to
      the JComboBox.DefaultKeySelectionManager.
      JComboBox's selection is conducted by selectionForKey method of
      JComboBox.DefaultKeySelectionManager interface, however this method
      isn't called when we input an em letter on the keyboard. So we ask
      whether the input of an em letter of Japanese Hiragana on the keyboard
      is refused on the jvm level, or even KeySelectionManager is not called
      when an em letter is inputed by key-board.
