JOSM loads the map source as a layer, or fails to fetch but remains responsive. ==== What happens instead? JSOM crashes ==== Please provide any additional information below. Attach a screenshot if possible. {{{ Revision:18678 Build-Date:2023-03-02 13:38:01 Identification: JOSM/1.5 (18678 en) Mac OS X 10.15.7 OS Build number: Mac OS X 10.15.7 (19H2026) Memory Usage: 2048 MB / 2048 MB (97 MB allocated, but free) Java version: 17.0.6+10-LTS, Azul Systems, Inc., OpenJDK 64-Bit Server VM Look and Feel: com.apple.laf.AquaLookAndFeel Screen: Display 69677248 1280×800 (scaling 1.00×1.00) Maximum Screen Size: 1280×800 Best cursor sizes: 16×16→16×16, 32×32→32×32 System property file.encoding: UTF-8 System property sun.jnu.encoding: UTF-8 Locale info: en_US Numbers with default locale: 1234567890 -> 1234567890 VM arguments: [-Djpackage.app-version=18678, --add-modules=java.scripting,java.sql,javafx.controls,javafx.media,javafx.swing,javafx.web, --add-exports=java.base/sun.security.action=ALL-UNNAMED, --add-exports=java.desktop/com.apple.eawt=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.spi=ALL-UNNAMED, --add-opens=java.base/java.lang=ALL-UNNAMED, --add-opens=java.base/java.nio=ALL-UNNAMED, --add-opens=java.base/jdk.internal.loader=ALL-UNNAMED, --add-opens=java.base/jdk.internal.ref=ALL-UNNAMED, --add-opens=java.desktop/javax.imageio.spi=ALL-UNNAMED, --add-opens=java.desktop/javax.swing.text.html=ALL-UNNAMED, --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED, -Djpackage.app-path=/Applications/JOSM.app/Contents/MacOS/JOSM] Dataset consistency test: No problems found Map paint styles: + https://josm.openstreetmap.de/josmfile?page=Styles/Lane_and_Road_Attributes&zip=1 - https://josm.openstreetmap.de/josmfile?page=Styles/MapillaryDetections&zip=1 - https://josm.openstreetmap.de/josmfile?page=Styles/PublicTransportV2&zip=1 + https://josm.openstreetmap.de/josmfile?page=Styles/SidewalksAndFootways&zip=1 Last errors/warnings: - 00101.390 E: Handled by bug report queue: java.lang.IllegalArgumentException: Vector tile layers must have a layer name - 00101.446 E: Handled by bug report queue: java.lang.IllegalArgumentException: Unknown field in vector tile layer value (31) - 00101.496 E: Handled by bug report queue: java.lang.IllegalArgumentException: Vector tile layers must have a layer name - 00101.496 W: Too many errors.
