Stack trace shows different exception type than print

[sheeba_weeba]

There are two exceptions being thrown:

1. json.loads('+Infinity') is called.
   
2. ...
   
3. raw_decode('+Infinity') is called.
   
4. raw_decode calls PositiveInfinityJSONDecoder._scan_once.
   
5. PositiveInfinityJSONDecoder._scan_once calls self.original_scan_once (a.k.a. JSONDecoder().scan_once).
   
6. self.original_scan_once raises a StopIteration as expected.
   
7. PositiveInfinityJSONDecoder._scan_once prints the StopIteration exception and reraises it.
   
8. raw_decode excepts StopIteration and raises JSONDecodeError.
   
9. JSONDecodeError is not caught, so it prints the stack trace for JSONDecodeError.
