Examples of org.springframework.batch.core.JobExecutionException

org.springframework.batch.core.JobExecutionException
Root of exception hierarchy for checked exceptions in job and step execution. Clients of the {@link Job} should expect to have to catch and deal with theseexceptions because they signal a user error, or an inconsistent state between the user's instructions and the data. @author Dave Syer
