Hi Nop, can you please test attatched patch? Ways without any nodes should be handled by the multipolygon handling so I moved the fix in the multipolygon code. How did you create such a file that contains ways without any nodes? WanMil
I have been debugging a crash of mkgamp where it fails with the exception
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.ArrayList.RangeCheck(Unknown Source) at java.util.ArrayList.get(Unknown Source) at uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation$JoinedWay.<init
(MultiPolygonRelation.java:2199) at uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation.joinWays(MultiP olygonRelation.java:245) at uk.me.parabola.mkgmap.reader.osm.MultiPolygonRelation.processElements (MultiPolygonRelation.java:763) at uk.me.parabola.mkgmap.reader.osm.ElementSaver.addRelation(ElementSave r.java:166) at uk.me.parabola.mkgmap.reader.osm.xml.Osm5XmlHandler$SaxHandler.endEle ment(Osm5XmlHandler.java:182)
The reason seems to be inconsistent data: a way without the nodes it references. As mkgmap siletntly drops missing ways, but crashes on missing nodes I assume this is a bug.
This can be fixed by changing Osm5XmlHandler, line 263 to
if ("way".equals(type)){ el = saver.getWay(id); // remove ways without points if( el != null && ((Way)el).getPoints().isEmpty() ) el = null; }
Maybe someone would like to apply this fix to make mkgmap more robust.
bye Nop
