In general it is inadvisable to use Exceptions to implement conditional flow. It would be better to do something like this

  error = false;
  while(true) {
    if(validCheckOne == false) { 
       msg = "Check one is bad"; 
       error = true;
       break;
    }

    if(validCheckTwo == false) { 
       msg = "Check two is bad"; 
       error = true;
       break;
    }
    ...
    break;
  }
  if (error) {
     ..
  }

You should throw an exception when there is a situation you can't do nothing about it. Higher layers of software would have a chance to catch the exception and do something about it - even if that is simply crashing the application.
