I did svn co https://josm.openstreetmap.de/svn/trunk/ and ran ""ant"" in there. I did build r15937 (and a bunch of version before that) and worked normally. When building r16239 the generated jar file will start but trying to download anything will fail with a crash: {{{ 2020-04-30 18:38:19.285 INFO: Obtained 57 Tag2Link rules from https://josm.openstreetmap.de/remote/wikidata-sparql 2020-04-30 18:38:19.325 INFO: Obtained 11 Tag2Link rules from https://josm.openstreetmap.de/remote/sophox-sparql Warning: Nashorn engine is planned to be removed from a future JDK release 2020-04-30 18:38:28.332 INFO: Changeset updater active (checks every 60 minutes if open changesets have been closed) 2020-04-30 18:38:28.332 INFO: Enabled EDT checker, wrongful access to gui from non EDT thread will be printed to console 2020-04-30 18:38:33.673 SEVERE: Handled by bug report queue: java.lang.NoClassDefFoundError: Could not initialize class org.openstreetmap.josm.data.cache.JCSCacheManager java.lang.NoClassDefFoundError: Could not initialize class org.openstreetmap.josm.data.cache.JCSCacheManager at org.openstreetmap.josm.gui.layer.AbstractCachedTileSourceLayer.getCache(AbstractCachedTileSourceLayer.java:118) at org.openstreetmap.josm.gui.layer.AbstractCachedTileSourceLayer.getTileLoaderFactory(AbstractCachedTileSourceLayer.java:106) at org.openstreetmap.josm.gui.bbox.JosmMapViewer.(JosmMapViewer.java:148) at org.openstreetmap.josm.gui.bbox.SlippyMapBBoxChooser.(SlippyMapBBoxChooser.java:87) at org.openstreetmap.josm.gui.download.SlippyMapChooser.(SlippyMapChooser.java:35) at org.openstreetmap.josm.gui.download.DownloadDialog.buildMainPanel(DownloadDialog.java:128) at org.openstreetmap.josm.gui.download.DownloadDialog.(DownloadDialog.java:230) at org.openstreetmap.josm.gui.download.DownloadDialog.(DownloadDialog.java:218) at org.openstreetmap.josm.gui.download.DownloadDialog.getInstance(DownloadDialog.java:84) at org.openstreetmap.josm.actions.DownloadAction.actionPerformed(DownloadAction.java:35) at java.desktop/javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:1967) at java.desktop/javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2308) at java.desktop/javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:405) at java.desktop/javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:262) at java.desktop/javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:279) at java.desktop/java.awt.AWTEventMulticaster.mouseReleased(AWTEventMulticaster.java:297) at java.desktop/java.awt.Component.processMouseEvent(Component.java:6631) at java.desktop/javax.swing.JComponent.processMouseEvent(JComponent.java:3342) at java.desktop/java.awt.Component.processEvent(Component.java:6396) at java.desktop/java.awt.Container.processEvent(Container.java:2263) at java.desktop/java.awt.Component.dispatchEventImpl(Component.java:5007) at java.desktop/java.awt.Container.dispatchEventImpl(Container.java:2321) at java.desktop/java.awt.Component.dispatchEvent(Component.java:4839) at java.desktop/java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4918) at java.desktop/java.awt.LightweightDispatcher.processMouseEvent(Container.java:4547) at java.desktop/java.awt.LightweightDispatcher.dispatchEvent(Container.java:4488) at java.desktop/java.awt.Container.dispatchEventImpl(Container.java:2307) at java.desktop/java.awt.Window.dispatchEventImpl(Window.java:2772) at java.desktop/java.awt.Component.dispatchEvent(Component.java:4839) at java.desktop/java.awt.EventQueue.dispatchEventImpl(EventQueue.java:772) at java.desktop/java.awt.EventQueue$4.run(EventQueue.java:721) at java.desktop/java.awt.EventQueue$4.run(EventQueue.java:715) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:85) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:95) at java.desktop/java.awt.EventQueue$5.run(EventQueue.java:745) at java.desktop/java.awt.EventQueue$5.run(EventQueue.java:743) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:85) at java.desktop/java.awt.EventQueue.dispatchEvent(EventQueue.java:742) at java.desktop/java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:203) at java.desktop/java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:124) at java.desktop/java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:113) at java.desktop/java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:109) at java.desktop/java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) at java.desktop/java.awt.EventDispatchThread.run(EventDispatchThread.java:90) }}} I tried this on two different machines (20.04 and 18.04) with the same result. With jdk 8/11/14. I also tried to checkout r15937 to bisect but this checkout fails with: {{{ svn: warning: W170000: URL 'https://github.com/apache/commons-jcs/trunk/commons-jcs-core/src/main/java/org/apache/commons/jcs' at revision 3137 doesn't exist }}} Any hints what I can do to get to a working build would be greatly appreciated. Do I need to update anything on my side how I build josm? Thanks, Michael" defect closed normal 20.05 Core fixed jcs cache logging serviceloader services meta-inf simon04 Don-vip
