Examples of org.springframework.batch.core.JobInterruptedException

org.springframework.batch.core.JobInterruptedException
Exception to indicate the the job has been interrupted. The exception state indicated is not normally recoverable by batch application clients, but internally it is useful to force a check. The exception will often be wrapped in a runtime exception (usually {@link UnexpectedJobExecutionException} beforereaching the client. @author Lucas Ward @author Dave Syer
