[Building Sakai] Empty response after exception in RequestFilter

[Steve Swinsburg]

Hi Daniel,

You might want to disable the RequestFilter from parsing file uploads This
needs to be done for some frameworks that handle their own uploads (like
Wicket) otherwise the RF eats them. In your web.xml RF declaration:

<init-param>
	<param-name>upload.enabled</param-name>
	<param-value>false</param-value>
</init-param>
