Following test case fails

import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.ProxySelector;
import java.net.URI;
import java.net.URISyntaxException;
import jdk.incubator.http.HttpClient;
import jdk.incubator.http.HttpRequest;
import jdk.incubator.http.HttpResponse;

public class Get {
    public static void main(String[] args)
            throws IOException, URISyntaxException, InterruptedException
    {
        //HttpClient client = HttpClient.newHttpClient();
        ProxySelector ps = ProxySelector.of(new InetSocketAddress("someproxy", 80));
        System.out.println(ps);
        HttpClient client = HttpClient.newBuilder()
                .proxy(ps)
                .build();
        System.out.println(client.proxy().orElse(null));

        HttpRequest request = HttpRequest.newBuilder()
            .GET()
            .uri(new URI("https://someuri/"))
            .build();

        HttpResponse<String> response
            = client.send(request, HttpResponse.BodyHandler.asString());
        System.out.println(response);
    }
}

fails with ClassCastException.

The CCE probably was introduced by the last change to this code base.
