> The following test fails on Harmony M10 but passes on the RI
> public class URLTest {
>     // Bogus handler forces file part of URL to be null
>     static class MyHandler extends URLStreamHandler {
>         @Override
>         protected URLConnection openConnection(URL arg0) throws IOException {
>             return null;
>         }
>         @Override
>         protected void setURL(URL u, String protocol, String host, int port,
>                 String authority, String userInfo, String file, String query,
>                 String ref) {
>             super.setURL(u, protocol, host, port, authority, userInfo,
>                     (String) null, query, ref);
