Instead of using getMessage(key, arg0, arg1, etc, etc....

use getMessage(key, args[])

<my-best-guess>
The default implementation of MessageResources (PropertyMessageResources)
does not provide for any way to manipulate the underlying HashMap at
runtime.

However, I guess you could hack around this with your own implementation
(not recommended).  Myself and a few others are looking at creating a
JDBCMessageResources that will probably provide a reload method.  So, I
guess, in a way that would allow someone to modify at runtime.
