Wondering if we need to update the sample code

https://github.com/Azure-Samples/ms-identity-msal-java-samples/blob/9c173abaa9643d8d4b5e5507196f7b3c33a5688b/3.%20Java%20Servlet%20Web%20App%20Tutorial/2-Authorization-I/call-graph/src/main/java/com/microsoft/azuresamples/msal4j/helpers/GraphHelper.java#L46

I followed this pattern in my code and I'm facing an issue where I got the "java.net.SocketTimeoutException: Read timed out" exception, then I google the issue, somebody from Microsoft suggested this way

```
public static GraphServiceClient getGraphClient(String accessToken, boolean force) throws ClientException {
if (client == null || force) {
client = GraphServiceClient.builder()
.authenticationProvider(new MsalGraphAuthenticationProvider(accessToken))
.buildClient();
}

return client;
}
```

Basically create few clients as less as we can, but I still got that exception constantly.

Any thoughts as to how to resolve this exception?
Thanks!

Start with the linked GraphHelper.java entry point around line 46 and compare its client construction with the suggested GraphServiceClient pattern. Reproduce the java.net.SocketTimeoutException: Read timed out, then determine whether the sample needs an update or whether the issue requires separate usage guidance; done means the cause and resolution are documented.
