How do I get a JEditorPane to highlight the full width of a line (not just the text)?

Question

I'm trying to get a JEditorPane to highlight the full width of a displayed line. All the examples I've tried only highlight the textual content. For example if I have content such as this:

 ---------------------------------
|Here is some text                |
|some more text                   |
 ---------------------------------

within a JEditorPane represented by the box above, then highlighting the first row highlights only the 'Here is some text' (represented between [ and ] below).

 ---------------------------------
[Here is some text]               |
|some more text                   |
 ---------------------------------

I would like it to highlight the full width of the JEditorPane like the following:

 ---------------------------------
[Here is some text                ]
|some more text                   |
 ---------------------------------

Is there a way to do this?

To prevent selection highlighting from interfering with VonC's solution I added the following line to the TextHighlight constructor (essentially making the selection highlight invisible):

textPane.setSelectionColor(new Color(1.0f, 1.0f, 1.0f, 0.0f));
