      Description

      We just upgraded from 4.2 to 4.8.1 and now run into an issue where added documents are not visible after doing a soft commit. Seems to be introduced by SOLR-5783.

      Problem manifests if conig explicitly sets nrtMode to false

      The setup of the index is fairly simple; single core, no cloud, no replication, java program that adds a few rows, concludes with a softcommit, hardcommit is done via autoCommit few times an hour. Another (similar) index that uses autoSoftCommit instead of softcommitting via code has the same issue. Here is a snippet of the log:
