I don't understand the answer here: https://github.com/aws/aws-sdk-java-v2/issues/4386#issuecomment-1712361944

Can someone please explain why this 'connection pool shut down' error occurs after 1 hour?

Why after 1 hour (and not 30 minutes)?
Has closing the defaultCredentialsProvider closed something that 'persists' across iterations of the for loop?

Ok I do understand it now but it required poking through the source code.

The key thing is that repeated calls to DefaultCredentialsProvider.create() return the same provider.

private static final DefaultCredentialsProvider DEFAULT_CREDENTIALS_PROVIDER = new DefaultCredentialsProvider(builder());

And then once closed, it's closed. So you need to be very careful how/where you use DefaultCredentialsProvider.create()
