Version mkgmap-r4315 was committed by gerd on Mon, 21 Oct 2019 code cleanup: remove obsolete call of Collections.sort() after call of MdrUtils.sortList() which already does this. Those lists are very small, so the obsolete sort did not cause performance problems http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4315
