I needed to revert to version 2715. ...2716 is the version which really breaks on my styles. There are for sure quite a lot serious bugs in 2716 and later... I'm sorry that I cannot relly help on tracking down the bugs - I'm currently in China, and haven't got much time, nor anything that we would consider usable internet in Europe (cannot reach my own SVN for example and lots of other things blocked - VPNs working unrealiably for productive tasks, and speed is max 256Kbit up, 2-3Mbit down) -- on the up to date - merge-roads rev 2722 many of my maps fail to compile - the usual is like countless errors due to identical road id (and rev 2721 really made this much worse. With 2717 I only get like 20 for Switzerland instead of uncountable), then (not for all countries) java.lang.assertionError: SEVERE (StyledConverter): c:\openmtbmap\maps\63710216.osm.pbf: Road with identical id: 238840783 ..... uncountable amount of, then: java.lang.AssertionError at uk.me.parabola.mkgmap.osmstyle.housenumber.HousenumberGenerator.match(HousenumberGenerator.java:322) at uk.me.parabola.mkgmap.osmstyle.housenumber.HousenumberGenerator.generate(HousenumberGenerator.java:195) at uk.me.parabola.mkgmap.osmstyle.StyledConverter.end(StyledConverter.java:389) at uk.me.parabola.mkgmap.reader.osm.ElementSaver.convert(ElementSaver.java:244) at uk.me.parabola.mkgmap.reader.osm.bin.OsmBinMapDataSource.load(OsmBinMapDataSource.java:67) at uk.me.parabola.mkgmap.reader.osm.OsmMapDataSource.load(OsmMapDataSource.java:127) at uk.me.parabola.mkgmap.main.MapMaker.loadFromFile(MapMaker.java:167) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:63) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:243) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:239) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) java.lang.AssertionError at uk.me.parabola.mkgmap.osmstyle.housenumber.HousenumberGenerator.match(HousenumberGenerator.java:322) at uk.me.parabola.mkgmap.osmstyle.housenumber.HousenumberGenerator.generate(HousenumberGenerator.java:195) at uk.me.parabola.mkgmap.osmstyle.StyledConverter.end(StyledConverter.java:389) at uk.me.parabola.mkgmap.reader.osm.ElementSaver.convert(ElementSaver.java:244) at uk.me.parabola.mkgmap.reader.osm.bin.OsmBinMapDataSource.load(OsmBinMapDataSource.java:67) at uk.me.parabola.mkgmap.reader.osm.OsmMapDataSource.load(OsmMapDataSource.java:127) at uk.me.parabola.mkgmap.main.MapMaker.loadFromFile(MapMaker.java:167) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:63) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:243) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:239) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) java.lang.AssertionError at uk.me.parabola.mkgmap.osmstyle.housenumber.HousenumberGenerator.match(HousenumberGenerator.java:322) at uk.me.parabola.mkgmap.osmstyle.housenumber.HousenumberGenerator.generate(HousenumberGenerator.java:195) at uk.me.parabola.mkgmap.osmstyle.StyledConverter.end(StyledConverter.java:389) at uk.me.parabola.mkgmap.reader.osm.ElementSaver.convert(ElementSaver.java:244) at uk.me.parabola.mkgmap.reader.osm.bin.OsmBinMapDataSource.load(OsmBinMapDataSource.java:67) at uk.me.parabola.mkgmap.reader.osm.OsmMapDataSource.load(OsmMapDataSource.java:127) at uk.me.parabola.mkgmap.main.MapMaker.loadFromFile(MapMaker.java:167) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:63) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:243) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:239) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
