Spring batch job is not terminating after adding Splunk logging step - spring-batch

Question

I am running a Spring batch but for logging purposes, I am redirecting all my logs to Splunk. The logs are getting updated on Splunk as expected, but now my job is not terminating. Even after everything gets processed, it's still running.
How can I terminate my job with Splunk logging enabled?

JobBuilderConfig.java
// Job
#Bean
public Job job(){
return jobBuilderFactory.get("jobCSProvMI4275")
.start(step1())
.next(step2())
.next(step3())
.next(step4())
.next(step5())
.next(step6())
.next(step7())
.incrementer(new RunIdIncrementer())
.build();
}
}
One workaround I am considering is to include jobListener and call system.exit(0) in the code itself. This seems to work fine, as it's terminating job even with Splunk logging enabled, but not sure if there is a better way to achieve this (ie exit the process gracefully).
#Bean
public JobExecutionListener jobMi4275ExecutionListener() {
JobExecutionListener jobExecutionListener = new JobExecutionListener() {
#Override
public void beforeJob(JobExecution jobExecution) {
LOGGER.info("jobCSP4275 Started executing..");
}
#Override
public void afterJob(JobExecution jobExecution) {
LOGGER.info("jobCSP4275 finished successfully..Exiting job !!");
System.exit(0);
}
};
return jobExecutionListener;
}
