Description

I wrote the following simple_server.pde and simple_client.pde using "processing.net.*;" but their behaviors seem to be strange.
The simple_client.pde seems to receive "Hi" and "Yes".
Am I missing something?

// simple_server
import processing.net.*;
Server svr;

void setup() {
  svr = new Server(this, 5555); 
  size(450, 255);
}

void draw() {
  Client c = svr.available();
  if (c != null) { 
    String s = c.readString(); // 読み込む
    println(s);
    svr.write("Yes");
  }
}

// simple_client
import processing.net.*; 
Client c; 

void setup() { 
  c = new Client(this,"127.0.0.1", 5555);
  size(450, 255);
} 

void draw() {
  if (c.available() > 0){
    String s = c.readString(); 
    println(s);
  }
}

void mouseClicked() {
  c.write("Hi"); 
}

Expected Behavior

"Hi" should be displayed in the console of the simple_server and "Yes" should be in the console of the simple_client.
Processing 3.4 has this behavior but Processing 3.5 (4.0a3) doesn't.

Current Behavior

Both "Hi" and "Yes" are displayed in the console of the simple_client.

Steps to Reproduce

1. Execute the simple_server.
2. Execute the simple_client.
3. Click the simple_clinet window.

Your Environment

• Processing version: Processing 3.5.4 (4.0a3)
• Operating System and OS version: Windows 10 Pro, version 2004, build, 19041.804
• Other information: Processing 3.4 seems to behave as expected.
