/**
 * Pluggable provider of {@link java.util.concurrent.ExecutorService executor services} used to run
 * Jersey request and response processing code.
 * 
 * When Jersey receives a request for processing, it will use the
 * {@link RequestExecutorsProvider request executor} to run the request
 * pre-processing and request-to-response transformation code. Once the response
 * is available, Jersey will use the {@link #getRespondingExecutor() responding
 * executor} to run the response post-processing code, before the final response
 * is returned to the application layer.
 * 

 * 

 * The custom provider implementing this interface should be registered in the standard way on the server.
 * The client must be created with configuration containing the provider, later registrations will be ignored.
