There's another frequently occurring exception in the log that occurs

This is a bug, but I am not sure where exactly.
An application should not try to write both to the Servlet's writer and
outputStream in the same response.
The easiest way to debug is to put a breakpoint at
ResponseFacade#getWriter() and ResponseFacade#getOutputStream() and see
what happens.
The TextChoiceProvider is writing to the outputstream. Is that what you
wanted to know?

The autocomplete works as expected so it doesn't trouble the user.
Anybody else getting this exception or does it depend on our configuration?
