Steps to reproduce

1. Install Wildfly from scratch
2. Add a new application user test with password test to standalone\configuration\application-users.properties

   ./add-user.sh -a -u test -p test -g testUserRole
   

3. Launch Wildfly using bin/standalone.bat
4. Deploy the attached web-application attached helloworld.war
5. With the following TestHttp2Client.java Java client:

   import java.net.Authenticator;
   import java.net.PasswordAuthentication;
   import java.net.URI;
   import java.net.http.HttpClient;
   import java.net.http.HttpClient.Version;
   import java.net.http.HttpRequest;
   
   public class TestHttp2Client {
   
   	public static void main(String[] args) throws Throwable {
   		System.setProperty("jdk.httpclient.HttpClient.log","all");
   	
   		Authenticator auth = new Authenticator() {
   		    @Override
   		    protected PasswordAuthentication getPasswordAuthentication() {
   		      return new PasswordAuthentication("test","test".toCharArray());
   		    }
   		};
   		
   		HttpRequest rq = HttpRequest.newBuilder(new URI("http://localhost:8080/helloworld/index.jsp")).GET().build();
   		HttpClient client = HttpClient.newBuilder().version(Version.HTTP_2).authenticator(auth).build();		
   		HttpResponse<String> response = client.send(rq, BodyHandlers.ofString());
   		System.out.println(response);
   	}	
   }
   

Compile and run the class with JDK-11:

javac TestHttp2Client.java
java javac TestHttp2Client.java

6. Check the communication error:
