[Building Sakai] Empty response after exception in RequestFilter

[Daniel Merino]

Thanks, Steve, but it is not the case. I need RequestFilter to handle 
uploads because I am adding methods to Resources classes. I just need to 
take control over Response when this error happens.

I think that the better way will be fixing the issue in the client side, 
not sending a request if an empty multipart is detected.

Thanks anyway!
Best regards.
