Version mkgmap-r4188 was committed by gerd on Sun, 13 May 2018 Fix problem with JRE 10 and newer: The ZipFile constructor throws NoSuchFileException instead of FileNotFoundException when a file doesn't exist. As a result mkgmap prints missleading error messages like "failed to get size for file N52E002.hgt from f:\srtm3\N52E002.hgt.zip" Now mkgmap first checks if the file exists before trying to open it as a ZipFile. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4188
