1.2.0.201109300915 I asked the 'Git Staging' view to refresh and then applied a patch. Some time later, an NPE occurred. org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException) at org.eclipse.swt.SWT.error(SWT.java:4283) at org.eclipse.swt.SWT.error(SWT.java:4198) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:138) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4140) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3757) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:972) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:888) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:90) at org.eclipse.ui.internal.Workbench$3.run(Workbench.java:559) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:519) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:123) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:344) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:624) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:579) at org.eclipse.equinox.launcher.Main.run(Main.java:1431) at org.eclipse.equinox.launcher.Main.main(Main.java:1407) Caused by: java.lang.NullPointerException at java.util.Arrays$ArrayList.<init>(Arrays.java:2842) at java.util.Arrays.asList(Arrays.java:2828) at org.eclipse.egit.ui.internal.staging.StagingViewContentProvider.inputChanged(StagingViewContentProvider.java:53) at org.eclipse.jface.viewers.ContentViewer.setInput(ContentViewer.java:276) at org.eclipse.jface.viewers.StructuredViewer.setInput(StructuredViewer.java:1690) at org.eclipse.egit.ui.internal.staging.StagingView$11$2.run(StagingView.java:495) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) ... 24 more
The error kept happening until I closed the view. Not sure if it would've came back if I reopened the view as I had shutdown Eclipse at that point.
