Bug 990484 - Error when hitting max retries

The max retry logic is flawed - if the user exits the retries it returns the range object (0..5) instead of an error or a value object.  Change logic so that retries can continue a certain number of times.
Add test case for retry to the max, also fix bad constant overrides
