> The final round of changes in HDFS-5673 switched to a search approach instead of a scan
approach for finding base access entries that need to be copied to the default ACL.  However,
in the case of doing full replacement on the default ACL, the list may not be sorted properly
at this point in the code, causing the searches to miss the access entries.
