Bug 64634 Navigate/Show in/Package Explorer doesn't work
With build I200405281200, if I select a Java file in the Navigator in the Java Perspective and then choose Navigate/Show in/Package Explorer, the Package Explorer is shown but the java file from the navigator is not visible or selected (i.e. the view doesn't expand the project or folder containing the java file).

return input.equals(selectionAsInput);
	}
	boolean showInput(Object input) {
		Object element= null;
			
		if (input instanceof IFile && isOnClassPath((IFile)input)) {
			element= JavaCore.create((IFile)input);
		}
				
		if (element == null) 
			element= input;
				
		if (element != null) {
			ISelection newSelection= new StructuredSelection(element);
			if (fViewer.getSelection().equals(newSelection)) {
				fViewer.reveal(element);
			} else {
				try {
					fViewer.removeSelectionChangedListener(fSelectionListener);						
					fViewer.setSelection(newSelection, true);
	
					while (element != null && fViewer.getSelection().isEmpty()) {
						
						element= getParent(element);
						if (element != null) {
