RegionUtil has to change some methods to switch old int/short value to new enums classes (like BorderStyle, HorizontalAlignment, FillPatternType...)

Actually, with version 3.15, we have some output lines like :
BorderStyle short usage

I use RegionUtil with merged zones, to put some border, with the following code :
protected static void addMergedRegion(Sheet sheet, int iRowMin, int iRowMax, int iColMin, int iColMax) {
    CellRangeAddress cellZone = new CellRangeAddress(iRowMin, iRowMax, iColMin, iColMax);
    sheet.addMergedRegion(cellZone);

    Cell cell = sheet.getRow(iRowMin).getCell(iColMin);
    if (cell != null) {
        RegionUtil.setBorderBottom(cell.getCellStyle().getBorderBottomEnum().getCode(), cellZone, sheet);
        RegionUtil.setBorderTop(cell.getCellStyle().getBorderTopEnum().getCode(), cellZone, sheet);
        RegionUtil.setBorderLeft(cell.getCellStyle().getBorderLeftEnum().getCode(), cellZone, sheet);
        RegionUtil.setBorderRight(cell.getCellStyle().getBorderRightEnum().getCode(), cellZone, sheet);

        RegionUtil.setBottomBorderColor(cell.getCellStyle().getBottomBorderColor(), cellZone, sheet);
        RegionUtil.setTopBorderColor(cell.getCellStyle().getTopBorderColor(), cellZone, sheet);
        RegionUtil.setLeftBorderColor(cell.getCellStyle().getLeftBorderColor(), cellZone, sheet);
        RegionUtil.setRightBorderColor(cell.getCellStyle().getRightBorderColor(), cellZone, sheet);
    }
}


Maybe, there is a new way to do the same thing, but I don't find it.
