Version mkgmap-r4323 was committed by gerd on Sat, 26 Oct 2019 code cleanup around sorting, no change in output expected - replace Collectors.sort(list[,...]) by list.sort([...]) - avoid new Comparator(..), use Java 8 functional interface instead as it is easier to understand http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4323
