Description

An all docs query that has a nonzero positive value in the start parameter will throw an NPE. Below is a slightly redacted query sent by the admin UI and the exception. This is from 9.2.0-SNAPSHOT installed as a service on Ubuntu, a user reported the problem on solr-user with the 9.1.0 docker image.
