That'll do it. It seems the FormAuthenticator expects that the POST
data is still in the input stream and hasn't been parsed.
You could try wrapping the request and re-inserting the data back into
the input stream, or you could patch saveRequest to save (and
subsequently re-load) the parameters.
Since you have broken the FormAuthenticator, you're going to have to
fix it.
It seems reasonable to request an enhancement to support this kind of
thing, so go ahead and file a Bugzilla enhancement request. Patches
are always welcome.
