    exception - the caused exception
    
    Returns:
    
    the exception found (or null if not found in the exception hierarchy)
  - createExceptionIterator
```
public static Iterator<Throwable> createExceptionIterator(Throwable exception)
```

    Parameters:
    
    exception - the exception
    
    Returns:
    
    the iterator

```

  - convertPrimitiveTypeToWrapperType
```
