Wrong Data Format (String) corrupts formatted values

[chpasha]

Library version 5.5.1:

cell, having number cell style defined as
#.##0,00 _€;[Red]-#.##0,00 _€
returns
#,##0.00_);[Red](#,##0.00)
on call to cell.getCellStyle().getDataFormatString - it corresponds to built-in style 40 (0x28)
negative values, formatted with this format by call to
DataFormatter.formatRawCellContents
return positive values in round brackets, so the value is effectively corrupted while using streaming event mode with XSSFSheetXMLHandler.

Here is the full code and sample file poi_formatting_problem.xls to reproduce the issue

try (var wb = WorkbookFactory.create(new File("poi_formatting_problem.xls")))
		{

			//Style (as seen in Excel) #.##0,00 _€;[Red]-#.##0,00 _€
			//is converted to #,##0.00_);[Red](#,##0.00)
			var sheet = wb.getSheetAt(0);
			var row = sheet.getRow(0);
			var cell = row.getCell(0);
			var str = new DataFormatter().formatRawCellContents(cell.getNumericCellValue(), cell.getCellStyle().getDataFormat(), 

cell.getCellStyle().getDataFormatString());
			//str is (378.13) instead of -378.13
		}
