Have you tried installing a custom `ErrorHandler`?
The 400 response should be generated by the ErrorHandler, and you
should be able to at least obtain a stack trace.

Other than that, in the DEBUG logs you should see the 400 response
being generated, and then you walk backwards on the same thread to see
what caused them.

Hope this helps.
