In awt.List select(int index) get unexpected behavior when the index param
is equal to -1. The last item in the list gets selected. When other invalid
values (-2) are used the call is ignored.

The same problem occurs with the deselect(int index) method.
If you add a few items to the list and call deselect with -1 as the index it
deselects the last item in the list.
