> If original path startsWith '/' it is removed by normalizePath; in that case 
> it should be added again URI-encoded. For example: A path value of 
> '/etc/motd' becomes:
> {code:java}
> ftp://myn...@host.dom/etc/motd{code}
> while it should be:
> {code:java}
> ftp://myn...@host.dom/%2Fetc/motd{code}
> Only when the path value is 'etc/motd' is should become 
> "ftp://myn...@host.dom/etc/motd";
>   
> Fix for this issue in URIBuilder.java:
> {noformat}
> private String buildString() {
> ...
>     if (this.encodedPath != null) {
>         sb.append(normalizePath(this.encodedPath, sb.length() == 0));
>     } else if (this.path != null) {
>         String encodedPath = encodePath(normalizePath(this.path, sb.length() 
> == 0));
>         // Start fix for paths starting with '/'
>         // If original path startsWith '/' it is removed by normalizePath; in 
> that case it should be added again URI-encoded.
>         if (this.path.startsWith("/")) {
>             encodedPath = "/%2F" + encodedPath.substring(1);
>         }
>         // End fix
>         sb.append(encodedPath);
>     }
