How to handle Exception from WebsocketTransport in cometD5?

[TienTungs295]

Hello everyone,
In cometD2 I have handled Exception by override handleException from WebSocketTransport class (cometd-websocket-jetty:2.9.0)
package cn.nextop.social.front.web.support.cometd;

import org.cometd.bayeux.server.ServerSession;
import org.cometd.server.BayeuxServerImpl;
import org.cometd.websocket.server.WebSocketTransport;
import org.eclipse.jetty.websocket.WebSocket;

import java.io.IOException;

public class CustomizedWebSocketTransport extends WebSocketTransport {
public CustomizedWebSocketTransport(BayeuxServerImpl bayeux) {
super(bayeux);
}

@Override
protected void handleException(WebSocket.Connection wsSession, ServerSession session, Throwable exception) {
	if (!(exception instanceof IOException)) super.handleException(wsSession, session, exception);
}

}

But after upgrading to cometD5 , the handleException function is removed in WebSocketTransport class (cometd-java-server-websocket-javax:5.0.0) and I cannot handle Exception .
Does anyone have a solution?
Thanks!

CometD 5 is at End of Community Support, see #1179.
You should upgrade to CometD 6 or CometD 7.

In CometD 5+, the method handleException() has been removed, since it was just logging the exception.
