A DESCRIPTION OF THE PROBLEM :
New API java.net.http doesn't support SOCKS. I tried sth like:

HttpClient.newBuilder().proxy(new ProxySelector() {
@Override
public List<Proxy> select(URI uri) {
return Arrays.asList(socks);
}

@Override
public void connectFailed(URI uri, SocketAddress sa, IOException ioe) {
System.out.println(socks + ": " + ioe);
}

})

but it goes direct. It doesn't show any error. Maybe add an error that socks is not supported or add socks support, please.
