Spring batch - java.lang.IllegalStateException: InputStream has already been read - do not use InputStreamResource

I have the below definition for FlatFileItemReader in s simple spring batch job:

@Bean
  public FlatFileItemReader<BookingInfo> bookingInfoReader() {
    FlatFileItemReader<BookingInfo> itemReader = new FlatFileItemReader<>();
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    BlobClient blobClient =
        blobContainerClient.getBlobClient("path/file.csv");
    blobClient.downloadStream(outputStream);
    final byte[] bytes = outputStream.toByteArray();
    ByteArrayInputStream inputStream = new ByteArrayInputStream(bytes);
    InputStreamResource resource = new InputStreamResource(inputStream);
    itemReader.setResource(resource);
    itemReader.setName("csvReader");
    itemReader.setLinesToSkip(1);
    itemReader.setLineMapper(lineMapper());
    return itemReader;
  }

But I get the error: java.lang.IllegalStateException: InputStream has already been read - do not use InputStreamResource if a stream needs to be read multiple times

Now, I changed the above code to use ByteArrayResource as shown below:

@Bean
  public FlatFileItemReader<BookingInfo> bookingInfoReader {

    FlatFileItemReader<BookingInfo> itemReader = new FlatFileItemReader<>();
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    BlobClient blobClient =
        blobContainerClient.getBlobClient("path/file.csv");
    blobClient.downloadStream(outputStream);
    final byte[] bytes = outputStream.toByteArray();
    ByteArrayInputStream inputStream = new ByteArrayInputStream(bytes);
    
    ByteArrayResource byteArrayResource = new ByteArrayResource(inputStream.readAllBytes());
    itemReader.setResource(byteArrayResource); 

    itemReader.setName("csvReader");
    itemReader.setLinesToSkip(1);
    itemReader.setLineMapper(lineMapper());
    return itemReader;
  }

Now the mentioned error goes away. However, there is a strange issue. Even if I update the file content, it is not fetching dynamically when the job is triggered. Instead, it is using the same old content. It takes modified content only after pod restart. I believe it is due to the fact that reader bean is created once and using it everytime.

So, I need to go back to InputStreamResource implementation by fixing the earlier mentioned issue. What is going wrong here?
