Using JobExecutionDecider with createOptionFlowUsingSteps - spring-batch

Question

I'm using createOptionFlowUsingSteps in my JobConfiguration and I've got 2 flows defined.
The first flow should always execute
If the first flow produces an empty output file, the job should end
If the file has contents, the second flow should begin
PROBLEM: the job is ending if the file is empty but if the file has contents, the job repeats the first flow and never performs the second flow.
Config
As you can see, I have startSteps and endSteps. Thank you for the help!
List<Step> startSteps = Arrays.asList( //
shp294SetupStep, // 0
deleteFileStep, // 1
callM204Step// 2
);
List<Step> endSteps = Arrays.asList( //
putFtpStep, // 0
cdtx500SetupStep, // 1
getFtpStep, // 2
callCobolStep, // 3
callSystemwareStep, //4
cdtx510SetupStep, // 5
getFtpStep, // 6
callCobolStep, // 7
putFtpStep// 8
);
List<Integer> emptyFileRequiredSteps = Arrays.asList(0);
List<Integer> requiredSteps = Arrays.asList(1, 5);
Flow startStepFlow = shpcdwrdStepHelper.createOptionalFlowUsingSteps(startSteps, emptyFileRequiredSteps);
Flow endStepFlow = shpcdwrdStepHelper.createOptionalFlowUsingSteps(endSteps, requiredSteps);
return jobFactory.get(JOB_NAME) //
.incrementer(new RunIdIncrementer()) //
.listener(new JobResultListener()) //
.start(startStepFlow) //
.next(optionalFlowDecider()).on(OptionalFlowDecider.ON_EMPTY_FILE).end() //
.from(optionalFlowDecider()).on(FlowExecutionStatus.COMPLETED.getName()).to(endStepFlow)
.build() //
.build(); //

In your flow definition, you should use the flow method to start your flow and define all outcomes from each transition, something like:
return jobFactory.get(JOB_NAME) //
.incrementer(new RunIdIncrementer()) //
.listener(new JobResultListener()) //
.flow(startStepFlow) //
.on(ExitStatus.COMPLETED.getExitCode()).to(optionalFlowDecider())
.from(optionalFlowDecider()).on(OptionalFlowDecider.ON_EMPTY_FILE).end() //
.from(optionalFlowDecider()).on(FlowExecutionStatus.COMPLETED.getName()).to(endStepFlow)
.build() //
.build(); //
