The "/" at the front of the path seems odd for a resource in a jar file,
usually it's a relative path that just happens to be from the root of
the jar file.
If the PropUtils can't find it, then it's likely there's something wrong
with the path. That's the method I use in OpenMap to load icons into
buttons.
