Some small code refactor:

[GoogleCodeExporter]

private void updateCheckBoxConstants(UIManager m, boolean focus, String append) 
{
        Image checkSel = m.getThemeImageConstant("checkBoxChecked" + append + "Image");
        if(checkSel != null) {
            Image checkUnsel = m.getThemeImageConstant("checkBoxUnchecked" + append + "Image");
            if(checkUnsel != null) {
                Image disUnsel = m.getThemeImageConstant("checkBoxUncheckDis" + append + "Image");
                Image disSel = m.getThemeImageConstant("checkBoxCheckDis" + append + "Image");
                if(disSel == null) {
                    disSel = checkSel;
                }
                if(disUnsel == null) {
                    disUnsel = checkUnsel;
                }
                if(focus) {
                    setCheckBoxFocusImages(checkSel, checkUnsel, disSel, disUnsel);
                } else {
                    setCheckBoxImages(checkSel, checkUnsel, disSel, disUnsel);
                }
            }
            if(checkUnsel != null) {
                if(focus) {
                    setCheckBoxFocusImages(checkSel, checkUnsel, checkSel, checkUnsel);
                } else {
                    setCheckBoxImages(checkSel, checkUnsel);
                }
            }
        }
    }

if(checkUnsel != null) { tested twice
