When a WebSocket connection is closed, the `await websocket.receive_text()` will raise a `WebSocketDisconnect` exception, which you can then catch and handle like in this example.

To try it out:

* Open the app with several browser tabs.
* Write messages from them.

**Exception Handling:**
```java
try {

} catch (Exception e) {
    throw new SuggesterException("Failed to initialize converter: "
                                + converter.getClass().getName(), e);
}
```

**Resource Management:**
```java
