http - java.net.URI chokes on special characters in host part -

I have a URI string like the following:

I am making java.lang.URI example with this string and it is successful, but when I want to retrieve the host it gives a blank return. Opera and Firefox have also messed up this URL if I am correctly reporting it as shown above. But is the URI class not invalidate the URIXXX?

.christlicheparteiösterreichs.at / steiermark /

Now it has been accepted by opera and Firefox But Java has been Still do not like it. How can I handle this type of URL?

Thanks

Java 6 class to work with international domain names Therefore, the following URI creates an encoded hostname:

  URI U = new URI ("http: //" + IDN.toASCII ("www.christlicheparteiösterreichs.at") + "/ Steermark / ");
