Description

Current server does 

 

if (Header) {    
  streams.computeIfAbsent(request.getStreamId(), id ->createStream());
  ...  
}

 

 

It is possible that clients send multiple headers so the entry already exists. We might choose to send a reply with error message without accepting duplicated headers.
