Description
I open a websocket like
url = ((window.location.protocol == "https:") ? "wss:" : "ws:") + "//" + window.location.host + path + "ws?pageId=6";
webSocket = new WebSocket(url);

in the controller I will read the parameter "pageId"

@serverendpoint(ContentPaths.websocketPath)
public class WebsocketController implements WebListener
{
@onopen
public void onOpen(final Session session)
{
final var params = session.getRequestParameterMap();
final var list = params.get("pageId");
}
}

The key "pageId" in session.getRequestParameterMap() ist not found. Instead the map contains 6=6.

In think in org.eclipse.jetty.websocket.core.Negotiated.Negotiated(URI, String, boolean, ExtensionStack, String)
the "map.put(field.getValue(), Collections.unmodifiableList(field.getValues()));"
should be " map.put(field.getName(), Collections.unmodifiableList(field.getValues()));"

How to reproduce?
