Consider this code snippet:

 @ResponseStatus(HttpStatus.NOT_FOUND)
 public class ProductNotFoundException extends RuntimeException {
     public ProductNotFoundException(Long id) {
         super("Product " + id + " not found");
     }
 }

 @GetMapping("/products/{id}")
 public Product getProduct(@PathVariable Long id) {
     return productRepo.findById(id).orElseThrow(() -> new ProductNotFoundException(id));
 }

What is the likely problem if the client always receives HTTP 500 instead of 404 when a product is missing?
