After upgrading Spring Cloud libraries to newest version Spring Cloud Config client behaves differently in terms of logging. In previous version, whenever Spring Cloud Config server was unavailable, I could see log:
Connect Timeout Exception on Url - http://localhost:8888/. Will be trying the next url if available
Currently there's no logs, application simply hangs. After Config Server is available, app also starts an emits all logs at once. It looks like it's caching somehow all logs istead of outputting it immediately.

In the example above, I was waiting for 30s, before starting Config Server (see timestamps). What is wrong?
