<Swing Dev> 6179357: Generics: JList: ListCellRenderer & prototypeCellValue

[Florian Brunner]

Here is a second sample.

It's not really a  real-world sample, but should be useful to show that also JList of other "value" 
types than String, such as Integer, Long and Short, can profit from generics.

It also shows why JList should specify
ListCellRenderer<? super E> cellRenderer

rather than

ListCellRenderer<E> cellRenderer

(Here: a common Number-cell renderer is used.)
