"Eclipse software update: NPE popup on saving edited source" To view the discussion, visit: https://community.jboss.org/message/731249#731249 -------------------------------------------------------------- Hello all, I've upgraded Eclipse 3.7 to the latest available software. I've never had big problems with that. I checked all that could be updated. Now however, I keep getting the following popup: https://community.jboss.org/servlet/JiveServlet/showImage/2-731249-18438/eclipse-update-npe-popup.png https://community.jboss.org/servlet/JiveServlet/downloadImage/2-731249-18438/450-268/eclipse-update-npe-popup.png Exception (copied from the Eclipse .log): !ENTRY org.eclipse.jface 4 2 2012-04-20 08:54:58.618 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface". !STACK 0 java.lang.NullPointerException at com.sun.enterprise.jst.server.sunappsrv.actions.PreludeUpdateCenterAction.accept(PreludeUpdateCenterAction.java:171) at com.sun.enterprise.jst.server.sunappsrv.actions.AppServerContextAction.selectionChanged(AppServerContextAction.java:238) at org.eclipse.ui.actions.SelectionProviderAction.selectionChanged(SelectionProviderAction.java:143) at org.eclipse.jface.viewers.Viewer$2.run(Viewer.java:164) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.internal.JFaceUtil$1.run(JFaceUtil.java:49) at org.eclipse.jface.util.SafeRunnable.run(SafeRunnable.java:175) at org.eclipse.jface.viewers.Viewer.fireSelectionChanged(Viewer.java:162) at org.eclipse.jface.viewers.StructuredViewer.updateSelection(StructuredViewer.java:2188) at org.eclipse.jface.viewers.StructuredViewer.setSelection(StructuredViewer.java:1725) at org.eclipse.jface.viewers.TreeViewer.setSelection(TreeViewer.java:1139) at org.eclipse.ui.navigator.CommonViewer.setSelection(CommonViewer.java:377) at org.eclipse.jface.viewers.Viewer.setSelection(Viewer.java:394) at org.eclipse.wst.server.ui.internal.cnf.ServerDecoratorsHandler$1.run(ServerDecoratorsHandler.java:58) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4140) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3757) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2701) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2665) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2499) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:679) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:668) 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(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) at org.eclipse.equinox.launcher.Main.main(Main.java:1386) Note this appears twice in the log, thus the two NPEs in the popup. When I edit any Java file a popup dialog appears *on every save operation while the JBoss 7 server is running*. It could hardly be more annoying to be honest! What's wrong here? Who's responsible? Is it a JBT issue at all? I have no idea. I cannot revert to the previous install, it fails with some error that some older Eclipse repos aren't found or so.
