Please install 3.1 M2 which fixes this problem. Note that now Cheetah plugin is no longer available. To get 1.5 features latest implementation, you have to get 3.1 milestone or integration builds. *** This bug has been marked as a duplicate of 68993 *** |
First an important note - I have the Cheetah (1.5) plugin installed. Cheetah contributes to the preferences page in question, so it may be to blame. I can reliably reproduce this bug on both RedHat Linux 9 and Windows XP. To reproduce this error, follow these steps: 1. Right click on a java or plugin project and select "Properties". 2. Select the "Java Compiler" preference page 3. Click "Use project settings" and click OK. 4. Eclipse will inform you of the need to do a full project build. Click "Yes". 5. The properties dialog will close. Right click on the project again and select "Properties" and return to the "Java Compiler" page. 6. Click "Use workspace settings" and click OK. 7. Eclipse will inform you again of the need to do a full project build. Click "Yes". 8. The properties dialog will close again. 9. Right click on the project A THIRD TIME (stay with me here!) Eclipse will open an error dialog with the title "Could Not Accept Changes" and the message "The currently displayed page contains invalid values". The Java Compiler page will not be visible. You'll also get the following stack trace: java.lang.IllegalStateException: Preference node "org.eclipse.jdt.core" has been removed. at org.eclipse.core.internal.preferences.EclipsePreferences.checkRemoved(EclipsePreferences.java:142) at org.eclipse.core.internal.preferences.EclipsePreferences.keys(EclipsePreferences.java:575) at org.eclipse.jdt.internal.core.JavaProject.getOptions(JavaProject.java:1438) at org.eclipse.jdt.internal.core.CompilationUnitProblemFinder.process(CompilationUnitProblemFinder.java:151) at org.eclipse.jdt.internal.core.CompilationUnitProblemFinder.process(CompilationUnitProblemFinder.java:206) at org.eclipse.jdt.internal.core.ReconcileWorkingCopyOperation.executeOperation(ReconcileWorkingCopyOperation.java:76) at org.eclipse.jdt.internal.core.JavaModelOperation.run(JavaModelOperation.java:700) at org.eclipse.jdt.internal.core.JavaModelOperation.runOperation(JavaModelOperation.java:739) at org.eclipse.jdt.internal.core.CompilationUnit.reconcile(CompilationUnit.java:1097) at org.eclipse.jdt.internal.ui.text.java.JavaReconcilingStrategy.reconcile(JavaReconcilingStrategy.java:88) at org.eclipse.jdt.internal.ui.text.java.JavaReconcilingStrategy.reconcile(JavaReconcilingStrategy.java:129) at org.eclipse.jdt.internal.ui.text.CompositeReconcilingStrategy.reconcile(CompositeReconcilingStrategy.java:86) at org.eclipse.jdt.internal.ui.text.JavaCompositeReconcilingStrategy.reconcile(JavaCompositeReconcilingStrategy.java:96) at org.eclipse.jface.text.reconciler.MonoReconciler.process(MonoReconciler.java:75) at org.eclipse.jdt.internal.ui.text.JavaReconciler.process(JavaReconciler.java:315) at org.eclipse.jface.text.reconciler.AbstractReconciler$BackgroundThread.run(AbstractReconciler.java:204)
