>             Project: Hadoop
>          Issue Type: Bug
>    Affects Versions: 0.5.0
>            Reporter: Thomas FRIOL
>            Priority: Minor
>             Fix For: 0.6.0

> Object obj = i.next();
> if (obj instanceof Path) {
>         sb.append((Path)obj);
> } else {
>         sb.append((String)obj);
> }
> If obj is an URL -> ClassCastException.
> Moreover, I think the test before appending the resource to the StringBuffer is not really necessary since the method take an Object as argument. Why not simply have :
> Object obj = i.next();
> sb.append(obj);
> I have attached a patch to fix this.
