JPA @Transactioanl REQUIRES_NEW AND Catch RuntimeException But rollback

@Service@RequiredArgsConstructor@Transactionalpublic class UserService {  public void createUser(CreateUserRequest request) {    Users users = firebaseUsersRepository.findUsersByFirebaseUid(request.getFirebaseUid())        .orElseThrow(() -> new BusinessException("Not Found User", HttpStatus.INTERNAL_SERVER_ERROR));    User user = User.builder()        .name(users.getDisplay_name())        .firebaseUid(request.getFirebaseUid())        .build();    userRepository.save(user);  }}@Component@RequiredArgsConstructor@Transactional(propagation = Propagation.REQUIRES_NEW)public class BaseEntityAuditAware implements AuditorAware<User> {  private final UserRepository userRepository;  @Override  public Optional<User> getCurrentAuditor() {    try {      return userRepository.findById(ApiLogger.getRequestCallerId());    } catch (Exception e) {      return Optional.empty();    }  }}

When calling userRepository.save(user) in createUser,After retrieving user information from BaseEntityAuditAware, which was implemented to use the JpaAudit function,Send an actual query.

At this time, the propagation property is REQUIRE_NEW, and all exceptions that occurred were caught.I expected that there would not be a rollback because the exception would not be passed to the parent function that called this function.In fact, an unexpectedrollbackexception occurred and the rollback occurred.

Returning null is not a problem,

In order to actually avoid raising an exception, I changed the above code as follows, and the insert query was successfully executed with a null value.

@Override@Transactional(propagation = Propagation.REQUIRES_NEW)  public Optional<User> getCurrentAuditor() {    Long callerId = ApiLogger.getRequestCallerId();    if (callerId == null)      return Optional.empty();    return userRepository.findById(ApiLogger.getRequestCallerId());  }

why rollback??

changed Transactional Option to@Transactional(propagation = Propagation.REQUIRES_NEW, noRollBackFor = Exception.class)but same.
