java.io.IOException: Invalid Http response

Now before you say there are questions like this I'd like to point out I've looked over most of them without any luck. Also I'm a first timer here so be gentle.

I have this annoyance right now in my current program:

Basically this part of my program uses a search engine to find torrent files.

public static ArrayList<String> search(String args) throws IOException {        
    args = args.replace(":", "");

    ArrayList<String> list = new ArrayList<String>();
    URL url = new URL("http://pirateproxy.net/search/" + args + "/");
    URLConnection con = url.openConnection();
    BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream())); <---- THIS
}

public static void main(String[] args) {
    try {
        search("The Hobbit: The Desolation of Smaug");
    } catch (IOException e) {
        e.printStackTrace();
    }
}

THE ERROR:

java.io.IOException: Invalid Http response
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
at service.ServiceDownloader.search(ServiceDownloader.java:20)
at service.ServiceDownloader.main(ServiceDownloader.java:45)

Now the fun part is that it ONLY goes wrong for this movie ("The Hobbit: The Desolation of Smaug"), every other movie works perfectly. I don't understand this. Please do help. (Also I have removed every unnecessary code from the search method)

If I did not put enough information here please ask me for more.

Instead of concatenating strings and needlessly creating interim strings and failing because the url is not encoded, you can use the built in UriBuilder to generate a valid URL

URL path = UriBuilder.fromPath("http://pirateproxy.net")
            .path("search")
            .path("some movie ")
            .build()
            .toURL();

// http://pirateproxy.net/search/some%20movie%20

I suspect it tripped on the colon (:) not the space. Are there other titles with a colon?

You should URL encode the String The Hobbit: The Desolation of Smaug, since you have special character there. Ex : space.
