Here is how you can reproduce it:
Server websocket:
package ad.ecs.websocket;
import java.io.IOException;
import javax.websocket.CloseReason;
import javax.websocket.OnClose;
import javax.websocket.OnError;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;
@ServerEndpoint(value = "/asyncMsg")
public class TestWebsocket {
@OnOpen
public void open(Session session) throws IOException{
session.getBasicRemote().sendText("Connection Established");
}
@OnMessage
public String login(String sessionID, Session session) {
// you can do this instead of exception and it will still leak memory
// try {
// session.close(new CloseReason(CloseCodes.GOING_AWAY, "Clearing
session"));
// } catch (IOException e) {
// e.printStackTrace();
// }
throw new IllegalArgumentException("Testing Leak");
}
@OnClose
public void close(Session session, CloseReason reason) {
}
@OnError
public void error(Session session, Throwable error) {
error.printStackTrace();
}
}
Here is the front end html:
<!DOCTYPE html>
<head>
<script type="text/javascript" src="app.js"></script>
</head>
<body>
<div>
<button onclick="test()">
LEAK
</button>
</div>
</body>
</html>
Here is js file:
var webSocket = null;
function test() {
console.log("test button clicked");
openSocket();
}
function openSocket() {
console.log("open webSocket");
webSocket = new WebSocket("ws://" + window.location.host +
"/memoryleak/asyncMsg");
webSocket.onopen = function(event){
console.log("webSocket open");
webSocket.send('test');
};
webSocket.onmessage = function(event){
console.log("webSocket onMessage", event);
};
webSocket.onclose = function(event){
webSocket = null;
console.log("webSocket connection closed", event);
openSocket();
};
}
function closeSocket(){
console.log("close webSocket");
if (webSocket)
webSocket.close();
}
You need to run it on multiple clients if you want it leak fast. We did it with
8 clients and it leaked 3GB with in like 10 min.
Thank you
