Do you consider this technique “BAD”?

Question

Sometimes you need to skip execution of part of a method under certain non-critical error conditions. You can use exceptions for that, but exceptions generally are not

Answer 1

If your code is doing something other than the plain meaning of the constructs in place, it's a good sign you've ventured into "cute" territory.

In this case you have a "loop" that will only run once. Any reader of the code will need to do a double-take to figure out what's going on.

If the case where it isn't "good" is truly exceptional, then throwing exceptions would be the better choice.
