(SelectionListDialog.sort) maxerickson@… team "==== What steps will reproduce the problem? 1. Tried to upload a large selection (~5000 objects) to split an import into coherent changesets. 2. 3. ==== What is the expected result? ==== What happens instead? ==== Please provide any additional information below. Attach a screenshot if possible. Obviously the workaround of ""Don't do that"" is easy. It would be nice if there were some support for dividing large numbers of changes by area instead of what seems to happen sometimes, where nodes are uploaded before ways. {{{ URL:http://josm.openstreetmap.de/svn/trunk Repository:UUID: 0c6e7542-c601-0410-84e7-c038aed88b3b Last:Changed Date: 2017-09-02 14:47:18 +0200 (Sat, 02 Sep 2017) Build-Date:2017-09-02 20:53:16 Revision:12712 Relative:URL: ^/trunk Identification: JOSM/1.5 (12712 en) Linux Arch Linux Memory Usage: 502 MB / 502 MB (204 MB allocated, but free) Java version: 1.8.0_144-b01, Oracle Corporation, OpenJDK Server VM Screen: :0.0 1280x800 Maximum Screen Size: 1280x800 VM arguments: [-Djosm.home=~/.josm-bulk] Dataset consistency test: No problems found Plugins: + apache-commons (33517) + buildings_tools (33004) + ejml (32680) + geojson (55) + geotools (33380) + jts (32699) + measurement (33088) + opendata (33553) + reverter (33572) + todo (30302) + undelete (33480) + utilsplugin2 (33579) + wikipedia (33626) Tagging presets: + ${HOME}/josm/my.presets.xml Map paint styles: + ${HOME}/josm/Style.BuildingYes.mapcss + https://josm.openstreetmap.de/josmfile?page=Styles/TigerReviewedNo&zip=1 Last errors/warnings: - W: Invalid jar file ''/plugins/geojson.jar.new'' (exists: false, canRead: false) - E: Failed to locate image 'tiger.png' - W: Mappaint style ""standard"" (My warning style) icon ""tiger.png"" not found. - W: Old style SideButton usage for action org.openstreetmap.josm.gui.io.UploadSelectionDialog$ContinueAction@2a6b87 - W: Old style SideButton usage for action org.openstreetmap.josm.gui.io.UploadSelectionDialog$CancelAction@18c4bf6 - W: Old style SideButton usage for action org.openstreetmap.josm.gui.help.ContextSensitiveHelpAction@17644e - E: Handled by bug report queue: java.lang.IllegalArgumentException: Comparison method violates its general contract! - E: Handled by bug report queue: java.lang.IllegalArgumentException: Comparison method violates its general contract! === REPORTED CRASH DATA === BugReportExceptionHandler#handleException: No data collected.
