Seen repeatedly in STS 2.5.2 rc2 whilst playing with a roo project java.lang.ClassCastException: org.eclipse.ajdt.core.javaelements.AspectElement cannot be cast to org.eclipse.contribution.xref.core.IXReferenceAdapter at org.eclipse.contribution.xref.core.XReferenceAdapterFactory.getAdapter(XReferenceAdapterFactory.java:33) at org.eclipse.core.internal.runtime.AdapterManager.getAdapter(AdapterManager.java:295) at org.eclipse.core.runtime.PlatformObject.getAdapter(PlatformObject.java:66) at org.eclipse.contribution.xref.internal.ui.utils.XRefUIUtils.getXRefAdapterListForJavaElement(XRefUIUtils.java:311) at org.eclipse.contribution.xref.ui.views.XReferenceView.selectionChanged(XReferenceView.java:177) at org.eclipse.ui.internal.AbstractSelectionService.firePostSelection(AbstractSelectionService.java:179) at org.eclipse.ui.internal.AbstractSelectionService$2.selectionChanged(AbstractSelectionService.java:71) at org.eclipse.jface.text.TextViewer.firePostSelectionChanged(TextViewer.java:2745) at org.eclipse.jface.text.TextViewer.firePostSelectionChanged(TextViewer.java:2693) at org.eclipse.jface.text.TextViewer$5.run(TextViewer.java:2672) at org.eclipse.swt.widgets.Display.runTimer(Display.java:4167) at org.eclipse.swt.widgets.Display.messageProc(Display.java:3256) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:2459) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3655) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2640) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2438) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:671) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:664) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) 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:369) 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:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407)
