Bug 239523 [TabbedProperties] Three JavaDoc warnings
I noticed there are three JavaDoc warnings in the org.eclipse.ui.views.properties.tabbed, there should be zero warnings and errors.
bundles/org.eclipse.ui.views.properties.tabbed/src/org/eclipse/ui/internal/views/properties/tabbed/view/OverridableTabListContentProvider.java
* Initialize the content provider for a tabbed property viewer.
	 * 
	 * @param tabbedPropertyViewer

	private void init(TabbedPropertyViewer newTabbedPropertyViewer) {
		this.tabbedPropertyViewer = newTabbedPropertyViewer;
		currentPart = tabbedPropertyViewer.getWorkbenchPart();
		if (currentPart.getAdapter(IPropertySheetPage.class) != null) {
			tabbedPropertySheetPage = (TabbedPropertySheetPage) currentPart
					.getAdapter(IPropertySheetPage.class);
		} else {
			/*
			 * Is the part is a IContributedContentsView for the contributor,
			 * for example, outline view.
			 */
			IContributedContentsView view = (IContributedContentsView) currentPart
					.getAdapter(IContributedContentsView.class);
			if (view != null) {
				IWorkbenchPart part = view.getContributingPart();
				if (part != null) {
					tabbedPropertySheetPage = (TabbedPropertySheetPage) part
							.getAdapter(IPropertySheetPage.class);
				}
			}
		}
		Assert
				.isNotNull(
						tabbedPropertySheetPage,
						"DynamicTabListContentProvider could not find the TabbedPropertySheetPage for the active part");
