>>> Because the JLabel is a custom class which wraps every control type, which gives them all a common border, which turns blue if they have focus.  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.

In my view, you are. A JLabel is for displaying text (and an optional
icon). A JPanel is a generic container. You should never have to add any
children to a JLabel. Your custom wrapper should extend JPanel instead.
Then everything else you wrote would make sense.
