I can't speak for Tomcat 9, but for T8 getParameter() won't work on a
multi-part form.  I vaguely recall there's a Tomcat way of getting the
parameters, but I ended up using Apache's FileUpload library which will
generate a list of files and parameters for the request.  Though I have no
idea if FileUpload will work with HTTP2 or not.
