Fixed version (ground truth):

  }
 else   if (StringUtils.isBlank(study.getStormpathDirectoryHref())) {

  }
 else   if (signUp == null) {
    throw new BridgeServiceException("String_Node_Str",HttpStatus.SC_BAD_REQUEST);
  }
 else   if (StringUtils.isBlank(signUp.getEmail())) {
    throw new BridgeServiceException("String_Node_Str",HttpStatus.SC_BAD_REQUEST);
  }
 else   if (StringUtils.isBlank(signUp.getPassword())) {
    throw new BridgeServiceException("String_Node_Str",HttpStatus.SC_BAD_REQUEST);
  }
 else   if (!emailValidator.isValid(signUp.getEmail())) {
    throw new BridgeServiceException("String_Node_Str",HttpStatus.SC_BAD_REQUEST);
  }
