Retry not working with FaultTolerantStepBuilder

Question

I am trying to build a retry into my error-prone itemreader. I have set up a small POC to test if everything is working, but I am not able to get retries running. Here is what I

Answer 1

"Am I doing something wrong or is this a bug?" seems like a bug. Oddly enough throwing the exception on write seems to be fine.

@Bean
public Job retrySample() {
    return jobBuilderFactory.get("retrySample").start(mockStep()).build();
}

@Bean
public Step mockStep() {

    return stepBuilderFactory.get("mockStep")
                .<String, String>chunk(1)
                .reader(itemReader()) 
                .writer(itemWriter())
                .faultTolerant()
                .retry(Exception.class)
                .retryLimit(10)

                .build();            

}

@Bean
@JobScope
public ItemReader<String> itemReader() {
    return new ItemReader<String>() {

        @Override
        public String read() throws Exception {
            return "dkafj";
        }
    };
}

@Bean
@JobScope
public ItemWriter<String> itemWriter() {
    return new ItemWriter<String>() {
        @Override
        public void write(List<? extends String> items) throws Exception {
            items.forEach(item -> {System.out.println("got" + item);});
            throw new Exception("booom");

        }
    };           
}
