This also makes each control a single control where they may otherwise be multiple controls.  ie a US phone number control has an area code input, a prefix input, a suffix input, and text labels to show the ( ) - mask.  One border shows around all of them.  Putting a single control like this JScrollPane in such a JPanel is to avoid duplicating logic like the border objects and focus listeners.
