    Description

      When you try to return a record from a remote EJB to a client you get an exception.

      Reproducer

      https://github.com/Adrodoc/wildfly-record-bug

      public class MyClient {
  public static void main(String[] args) throws Throwable {
    System.setProperty(INITIAL_CONTEXT_FACTORY, org.wildfly.naming.client.WildFlyInitialContextFactory.class.getName());
    System.setProperty(PROVIDER_URL, "remote+http://localhost:8080");
    MyInterface session = InitialContext.doLookup("server/" + MyInterface.NAME + "!" + MyInterface.class.getName());
    System.out.println(session.getString());
    MyRecord record = session.getRecord();
    System.out.println(record.title() + ": " + record.message());
  }
}

      public interface MyInterface {
  String NAME = "MyInterface";

  String getString();

  MyRecord getRecord();
}

      import java.io.Serializable;

public record MyRecord(String title, String message) implements Serializable {
}

      import javax.ejb.Remote;
import javax.ejb.Stateless;
import org.wildfly.bug.record.interfaces.MyInterface;
import org.wildfly.bug.record.interfaces.MyRecord;

@Remote(MyInterface.class)
@Stateless(name = MyInterface.NAME)
public class MyEjb implements MyInterface {
  @Override
  public String getString() {
    return "Hello World!";
  }

  @Override
  public MyRecord getRecord() {
    return new MyRecord("Greetings", "Hello World!");
  }
}

      Exception in server.log:
