/**
 * A {@link FactoryBean} that automates the creation of a
 * {@link SimpleJobRepository} using non-persistent in-memory DAO
 * implementations. This repository is only really intended for use in testing
 * and rapid prototyping. In such settings you might find that
 * {@link ResourcelessTransactionManager} is useful (as long as your business
 * logic does not use a relational database). Not suited for use in
 * multi-threaded jobs with splits, although it should be safe to use in a
 * multi-threaded step.
 * 
 * @author Robert Kasanicky
 * @author Mahmoud Ben Hassine
 * 
 * @deprecated as of v4.3 in favor or using the {@link JobRepositoryFactoryBean}
 * with an in-memory database. Scheduled for removal in v5.0.
