I am trying to set the font of a conditional formatting However when I run

FontFormatting font1 = rule1.createFontFormatting();
font1.setFontColor(new XSSFColor(new java.awt.Color(198, 239, 206)));

I get an IndexOutOfBoundsException Shown below.

Exception in thread "main" java.lang.IndexOutOfBoundsException 
at org.openxmlformats.schemas.spreadsheetml.x2006.main.impl.CTFontImpl.setColorArray(Unknown Source)
at org.apache.poi.xssf.usermodel.XSSFFontFormatting.setFontColor(XSSFFontFormatting.java:125)

The code that breaks is 
    @Override
    public void setFontColor(Color color) {
        XSSFColor xcolor = XSSFColor.toXSSFColor(color);
        if (xcolor == null) {
            _font.getColorList().clear();
        } else {
            _font.setColorArray(0, xcolor.getCTColor());
        }
    }



This stack overflow post is the only place I can find the issue mentioned, however I dont beleive they ever submitted a bug report
