Other Useful Methods
The {@link oajrc.RestClientBuilder#rootUrl(Object)} method can be used to specify a root URL on all requests so that you don't have to use absolute paths on individual calls.
The {@link oajrc.RestClientBuilder#set(String,Object)} method can be used to set serializer and parser properties. For example, if you're parsing a response into POJOs and you want to ignore fields that aren't on the POJOs, you can use the {@link oaj.BeanContext#BEAN_ignoreUnknownBeanProperties} property.
The {@link oajrc.RestCall#retryable(int,long,RetryOn)} method can be used to automatically retry requests on failures. This can be particularly useful if you're attempting to connect to a REST resource that may be in the process of still initializing.
