/**
 * Batch domain object representing a uniquely identifiable configured job.
 *
 * Cf https://docs.spring.io/spring-batch/apidocs/org/springframework/batch/core/JobInstance.html
 *
 * Please note the following difference between Spring Batch and Akeneo Batch,
 *
 * In Spring Batch: a JobInstance can be restarted multiple times in case of execution failure and it's lifecycle ends
 * with first successful execution. Trying to execute an existing JobInstance that has already completed successfully
 * will result in error. Error will be raised also for an attempt to restart a failed JobInstance if the Job is not restartable.
 *
 * In Akeneo Batch: the behavior is not the same, we store a JobInstance, we can run the Job then run it again with the
 * same config, change the config, then run it again.
