cajeta.error.NoOptionalValueException — thrown by Optional.get() on an empty Optional. Extends RecoverableException: an unwrap miss is catchable and the program continues — UnrecoverableException is reserved for panic. Prefer guarding with isPresent() or using orElse(); the type exists so an unguarded unwrap fails loudly at the fault site with a stable diagnostic code (the class FQN).

Optional<int32> miss = stack Optional<int32>(false, 0);
try {
    int32 v = miss.get();
} catch (NoOptionalValueException e) {
    // reached: unwrap of an empty Optional
}
