A DESCRIPTION OF THE PROBLEM :
HttpClient throws java.io.IOException: no statuscode in response when used with HTTP2 endpoint. Changing the version of request to HTTP 1.1 seems to fix the problem.

Stack trace seems to be similar in meaning to https://bugs.openjdk.org/browse/JDK-8263031?jql=text%20~%20%22no%20statuscode%20in%20response%22 which should be fix in opne-jdk 19. However I am still experiencing the problem - maybe the root cause is different.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use java code provided below to send a request via HttpClient.


---------- BEGIN SOURCE ----------
import java.io.IOException;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.net.http.HttpResponse.BodyHandlers;

public class Test {

    public static void main(String[] args) throws IOException, InterruptedException {

        String baseUri = "https://dawa.aws.dk/autocomplete?q=Rentemestervej+8,+2400+K%C3%B8benhavn+NV";
        HttpRequest build = HttpRequest
                .newBuilder(URI.create(baseUri))
                .build();

        HttpResponse<String> send = HttpClient.newHttpClient().send(build, BodyHandlers.ofString());
        String body = send.body();
    }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Changing the HTTP version to 1.1 by adding .version(HttpClient.Version.HTTP_1_1) when building HttpRequest object.

FREQUENCY : always
