Examples of org.springframework.batch.item.UnexpectedInputException

org.springframework.batch.item.UnexpectedInputException
Used to signal an unexpected end of an input or message stream. This is an abnormal condition, not just the end of the data - e.g. if a resource becomes unavailable, or a stream becomes unreadable. @author Dave Syer @author Ben Hale
