Copy an image to your clipboard (I took a screenshot with Spectacle on KDE, which copies the screenshot to my clipboard apparently). 2. Try to File > Download Object or Windwos > Changeset manager (this is hwere I report it from) ==== What is the expected result? There is no crash. ==== What happens instead? The actions launched by these commands crash. ==== Please provide any additional information below. Attach a screenshot if possible. AI suggests it is because my JAVA is too new, not sure about it. But it correctly advised me that clipboard was the problem. {{{ Relative:URL: ^/trunk Repository:UUID: 0c6e7542-c601-0410-84e7-c038aed88b3b Last:Changed Date: 2026-01-31 13:00:34 +0100 (Sat, 31 Jan 2026) Revision:19481 Build-Date:2026-02-01 02:30:45 URL:https://josm.openstreetmap.de/svn/trunk Identification: JOSM/1.5 (19481 en) Linux Fedora Linux 43 (KDE Plasma Desktop Edition) Memory Usage: 528 MB / 16008 MB (190 MB allocated, but free) Java version: 26-ea+32, Red Hat, Inc., OpenJDK 64-Bit Server VM Look and Feel: javax.swing.plaf.metal.MetalLookAndFeel Screen: :0.0 2182x1227x[Multi depth]@60Hz (scaling 2.00×2.00) :0.1 2560x1440x[Multi depth]@60Hz (scaling 2.00×2.00) :0.2 3840x2160x[Multi depth]@60Hz (scaling 2.00×2.00) Maximum Screen Size: 3840×2160 Best cursor sizes: 16×16→16×16, 32×32→32×32 Environment variable LANG: en_US.UTF-8 System property file.encoding: UTF-8 System property sun.jnu.encoding: UTF-8 Locale info: en_US Numbers with default locale: 1234567890 -> 1234567890 Desktop environment: KDE VM arguments: [--add-exports=java.base/sun.security.action=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.spi=ALL-UNNAMED, -Djava.util.prefs.userRoot=/java] Dataset consistency test: No problems found Plugins: + FastDraw (36474) + apache-commons (36474) + ejml (36474) + geotools (36474) + imagery_offset_db (36474) + jackson (36474) + jaxb (36474) + jts (36474) + opendata (36474) + pbf (36474) + scripting (v0.3.5) + utilsplugin2 (36474) Last errors/warnings: - 00026.184 E: Handled by bug report queue: java.lang.NoClassDefFoundError: sun/security/action/GetPropertyAction.
