Consider this client code:

     JList<String> list = ...;
     String[] strs = list.getSelectedValues();

In that code you have a ClassCastException from Object[] to String[].

Unfortunately you can *not*, for obscure language reasons, even declare 
JList<E>.getSelectedValues as:

     public <T super E> T[] getSelectedValues()

So, I think if you want the method genericisted, it needs to be 
deprecated (or as near as we are allowed) and replaced. Although for my 
money, you're always better off going for a model and leaving the actual 
JComponent well alone.
