I’ve inherited a Spring Batch job & am trying to understand the following behavior.

An exception was thrown in the configIBMTCompletionProcessor (ConfigIBMTCompletionProcessor.java)
of the VerifyPreditErrors step, & I’m expecting the job to stop as per the step definition. But this step was marked as ABANDONED & proceeded to the next step IBMTFileCopy.

Java definition

configIBMTCompletionWriter bean (ConfigIBMTCompletionWriter.java)

public class ConfigIBMTCompletionWriter implements ItemWriter<List<CustomParams>>,
    StepExecutionListener {

  @Override
  public void write(List<? extends List<CustomParams>> items) throws Exception {    
  ...
  }

  @Override
  public ExitStatus afterStep(StepExecution stepExecution) {
    logger.info("Setting the step status as: " + status);
    if (status.equals(Constants.SUCCESS)) {
      return new ExitStatus(Constants.SUCCESS);
    } else if (status.equals(Constants.FAILED)) {
      return new ExitStatus(Constants.FAILED);
    }
    return ExitStatus.NOOP;
  }

  @Override
  public void beforeStep(StepExecution stepExecution) {}
}

configIBMTCompletionProcessor bean (ConfigIBMTCompletionProcessor.java)

public class ConfigIBMTCompletionProcessor implements
    ItemProcessor<String, List<CustomParams>>, StepExecutionListener {
  // fetch data from DB
  String status = service.fetchBatchWorkStatus();

  case (status) {
    ...
    case Constants.FAILED:
      throw Exception(...);
    ...
  }
}

  @Override
  public void beforeStep(StepExecution stepExecution) {
    // some pre-processing 
  }

  @Override
  public ExitStatus afterStep(StepExecution stepExecution) {
    // TODO Auto-generated method stub
    return null;
  }

Questions

1. Why did the job proceed to the IBMTFileCopy step?

2. Why is the VerifyPreditErrors marked as ABANDONED?
