The host input method adapter for Win32 sometimes (not always) throws a null pointer exception on Japanese Windows98 with the following operations:

 - Start SwingSet demo
 - Select "File Chooser" from "Choosers" to bring the dialog
 - Select "ImageClub" -> "food" -> "banana.gif" by double click.
   (which bring up the message dialog)
 - Close the message dialog.

The stack trace is:
