Build ID: 3.3M5eh Steps To Reproduce: Twice now I've gotten stuck on startup with a NoClassDefFoundException. First time I wiped the configuration/ folder and it worked fine again. Second time I played some more with it and found out it is something in configuration/org.eclipse.update that is causing this exception (I will attach my zip of that folder to this bug). It might be OSX related since there is some font thing that is failing: Exception in thread "Thread-1" java.lang.NoClassDefFoundError at org.eclipse.ui.internal.themes.ThemeElementHelper.installFont(ThemeElementHelper.java:101) at org.eclipse.ui.internal.themes.ThemeElementHelper.populateRegistry(ThemeElementHelper.java:57) at org.eclipse.ui.internal.Workbench$26.runWithException(Workbench.java:1369) at org.eclipse.ui.internal.StartupThreading$StartupRunnable.run(StartupThreading.java:31) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:123) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3166) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2916) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2187) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2103) at org.eclipse.ui.internal.Workbench$4.run(Workbench.java:457) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:289) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:452) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:101) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:146) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:106) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:76) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:354) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:169) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:476) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:416) at org.eclipse.equinox.launcher.Main.run(Main.java:1124) More information:
Created attachment 60665 [details] config/org.eclipse.update that crashes eclipse on startup for me Hopefully this zip repros it without the rest of my environment.
I'm going to move this to Platform UI, it doesn't look like an update problem. The org.eclipse.update folder simply contains your platform configuration. It's highly likely that something you installed into your Platform causes the platform to crash. What was the last thing you installed into your platform before it crapped out on you?
And this is only happening with M5eh? Things were fine in M4 or earlier?
Without more info I can't proceed.
