AJAX Error: Request Failed: FULL head

I have been using Web Console for a while to configure my DS components. But recently, one of my component's metatype.xml file got larger due to increase in configuration options for the component. Suddenly, now when I try to configure that component, even without changing a value, I get an AJAX error. Although sometimes there is no message inside the AJAX Error dialog at all, I frequently get a "Request failed: FULL head" message in the AJAX Error modal dialog. I have searched around the internet and it looks like the cause of this is about the size of the Jetty's header buffer (http://jira.codehaus.org/browse/JETTY-336).

Any fix is appreciated as this prevents me from debugging configuration of my component.
