Bug 161848 [JFace] Javadoc quality in org.eclipse.jface
As Tod announced on the platform-ui mailing list he wants to set the compiler settings to stricter mode so to ensure the javadoc quality. Because the weather was so lousy in Austria today I tried it and took the effort (~2 hours). I'll attach the patches package wise. This is a starting point.
bundles/org.eclipse.jface/src/org/eclipse/jface/viewers/TreeViewer.java
protected void doUpdateItem(final Item item, Object element) {
		if (!(item instanceof TreeItem)) {
			return;
		}
		TreeItem treeItem = (TreeItem) item;
		if (treeItem.isDisposed()) {
			unmapElement(element, treeItem);
			return;
		}
		int columnCount = getTree().getColumnCount();
		if (columnCount == 0)
			columnCount = 1;
		for (int column = 0; column < columnCount; column++) {
			ViewerColumn columnViewer = getViewerColumn(column);
			columnViewer.refresh(updateCell(getViewerRowFromItem(treeItem),
					column));
			
			
			if (item.isDisposed()) {
				unmapElement(element, item);
				return;
			}
		}
