FileUploadException wrapped in wiketRuntime exception, why? is that a good practice?

Hi there, i have a question about FileUploadException.

In line 80 of MultipartServletWebRequest, the constructor throws
FileUploadException which is checked, and then in line 500 of
ServletWebRequest, it was wrapped to a wickerRuntimeException,

    @Override
    public WebRequest newMultipartWebRequest(Bytes maxsize)
    {
        try
        {
            MultipartServletWebRequest multipart = new
MultipartServletWebRequest(
                httpServletRequest, maxsize);
            multipart.setRequestParameters(getRequestParameters());
            return multipart;
        }
        catch (FileUploadException e)
        {
            throw new WicketRuntimeException(e);
        }
    }


is that a good practice?, why FileUploadException is a checked exception?
because it could be runtime exception because then it is wrapped anyway.
does anybody knows?

Thanks
NM
