Bug 90841 [misc] IllegalStateException in Java editor
build i0405 I got the following exception in my log file. I believe I did a ctrl-shift-u to turn off "mark occurances" (didn't realize that wasn't the right key binding) so then I hit the icon and now I get that message everytime I hit the "mark occurances" icon. It looks like JavaEditor.EclipsePreferencesAdaptor holds onto the preference node but this node has been removed. Nodes aren't handles, they are the real objects and shouldn't be cached like this. !ENTRY org.eclipse.ui.workbench 4 2 2005-04-08 14:43:57.926 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench". !STACK 0 java.lang.IllegalStateException: Preference node "org.eclipse.jdt.core" has been removed. at org.eclipse.core.internal.preferences.EclipsePreferences.checkRemoved(EclipsePreferences.java:146) at org.eclipse.core.internal.preferences.EclipsePreferences.internalGet(EclipsePreferences.java:501) at org.eclipse.core.internal.preferences.EclipsePreferences.get(EclipsePreferences.java:362) at org.eclipse.jdt.internal.ui.javaeditor.JavaEditor$EclipsePreferencesAdapter.contains(JavaEditor.java:362) at org.eclipse.ui.texteditor.ChainedPreferenceStore.getVisibleStore(ChainedPreferenceStore.java:528) at org.eclipse.ui.texteditor.ChainedPreferenceStore.handlePropertyChangeEvent(ChainedPreferenceStore.java:412) at org.eclipse.ui.texteditor.ChainedPreferenceStore.access$0(ChainedPreferenceStore.java:407) at org.eclipse.ui.texteditor.ChainedPreferenceStore$PropertyChangeListener.propertyChange(ChainedPreferenceStore.java:68) at org.eclipse.ui.preferences.ScopedPreferenceStore$3.run(ScopedPreferenceStore.java:339) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1021) at org.eclipse.core.runtime.Platform.run(Platform.java:757) at org.eclipse.ui.preferences.ScopedPreferenceStore.firePropertyChangeEvent(ScopedPreferenceStore.java:336) at org.eclipse.ui.preferences.ScopedPreferenceStore.setValue(ScopedPreferenceStore.java:736) at org.eclipse.jdt.internal.ui.javaeditor.ToggleMarkOccurrencesAction.run(ToggleMarkOccurrencesAction.java:54) at org.eclipse.jface.action.Action.runWithEvent(Action.java:996) at org.eclipse.ui.actions.RetargetAction.runWithEvent(RetargetAction.java:216) at org.eclipse.ui.internal.WWinPluginAction.runWithEvent(WWinPluginAction.java:228) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:538) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:488) at org.eclipse.jface.action.ActionContributionItem$6.handleEvent(ActionContributionItem.java:441) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:82) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:842) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:2894) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2527) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1570) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1534) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:306) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:143) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:103) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:228) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:344) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:156) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:85) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:58) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:60) at java.lang.reflect.Method.invoke(Method.java:391) at org.eclipse.core.launcher.Main.invokeFramework(Main.java:315) at org.eclipse.core.launcher.Main.basicRun(Main.java:268) at org.eclipse.core.launcher.Main.run(Main.java:947) at org.eclipse.core.launcher.Main.main(Main.java:931)
