Amazon replay logic in Amazon web services

Question

http://docs.aws.amazon.com/general/latest/gr/api-retries.html

This document mentions that "each AWS SDK implements automatic retry logic, and the AWS SDK for Java automatically repeats queries."

What is the default mechanism for the Java AWS SDK if I do not specify a retry configuration? I use the Java AWS SDK and get a simple service exception if something is not working on the AWS side. I have never experienced any “automatic” repeat mechanism. Can someone explain what the repetition mechanism is?
