Can one set a border around a GaugeField?

I'm trying to put a 1px border around a GaugeField to make it stand out. I'm using the code below, but it isn't having any effect.

SetBorder is in the api of GaugeField,开发者_运维知识库 but I'm not doing something right. Ideas?

    progressBar = new GaugeField(null,0,100,0,GaugeField.PERCENT);
    progressBar.setBorder(BorderFactory.createSimpleBorder(
            new XYEdges(1,1,1,1), 
            new XYEdges(0,0,0,0),
            Border.STYLE_FILLED));

It will have affect if you change from Border.STYLE_FILLED to Border.STYLE_SOLID.

The doc for BorderFactory.createSimpleBorder(XYEdges edges, XYEdges colors, int style) says:

style - STYLE_TRANSPARENT, STYLE_SOLID, SYLE_DOTTED, STYLE_DASHED.

Note there's no Border.STYLE_FILLED in that list.
