How to properly close the WebSocketClient@ thread problem?

[cuideyu]

Jetty Version
Jetty 9.4.53

Jetty Environment
linux
jetty run command: ./bin/jetty.sh run

Java Version
1.8.0_371 x64

Question
I used this code to create a Websocket client connection

WebSocketContainer container = ContainerProvider.getWebSocketContainer();
container.connectToServer(this, URI.create(url));

If the server connection fails, this code will continue to be used during the reconnection.
But each execution of this code creates eight threads of WebSocketClient@xxx-xxx
The connection pool cannot be automatically destroyed if the connection fails.
My code ContainerProvider.getWebSocketContainer();
-> org.eclipse.jetty.websocket.jsr356.ClientContainer<111 line> - > public ClientContainer()
-> WebSocketClient <95 line>-> public WebSocketClient()
-> DefaultHttpClientProvider.get
-> DefaultHttpClientProvider.newHttpClient

Reconnecting will create a new thread pool and 8 threads. How do I close this object? Can't you create a Websocket client this way in Jetty?

Jetty versions older than Jetty 12 are now at End of Community Support.

• EoCS (End of Community Support) for Jetty 9 - June 2022 #7958
• EoCS (End of Community Support) for Jetty 10 / Jetty 11 - January 2024 #10485

You should be using Jetty 12 at this point in time.

The WebSocket layer has been reworked entirely for Jetty 12 as well.
