Are you sure that the selection should be always cleared in this method, how it
will work if the jlist supports multiline selection? Or voice over does not
support multyline selection?
As a fix, you can delete listeners from the jlist so your request to clear the
current selection will not be sent back to the voiceover. Or you can add a new
method to the AccessibleSelection interface with the default implementation
"clearAccessibleSelection+addAccessibleSelection". Then override it in the
jlist to call setSelectedIndex().
