> Having the retry logic within the `finally` block seems like the best way of denoting the intention to me, since the intention is to swallow the result, whether that was a return or a throw.
Except that is not the documented intent of the `finally` construct:
The finally block always executes when the try block exits.
This ensures that the finally block is executed even if an
unexpected exception occurs. But finally is useful for more
than just exception handling — it allows the programmer to
avoid having cleanup code accidentally bypassed by a
return, continue, or break. Putting cleanup code in a
finally block is always a good practice, even when no
exceptions are anticipated.[0]
Using `finally` for implementing retry logic can be done, as you have illustrated, but that does not mean it is "the best way of denoting the intention." One could argue this is a construct specific to Java (the language) and does not make sense outside of this particular language-specific idiom.
Conceptually, "retries" are not "cleanup code."
