RAW_XML_FILE_HEADER

It´s the same problem, the firts time that I executed the script show me RAW_XML_FILE_HEADER error, but the followings times, show me:

"java.langNoClassDefFoundError:Could not initialize class org.apache.poi.poifs.filesystem.Magic error at line 14"

import java.io.File;
import java.io.FileInputStream;
import java.util.Iterator;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;

String filepath = "D:\\prueba_estila\\Parametros1.xlsx"
String sheetName = "Sheet1"
FileInputStream fis = new FileInputStream(new File(filepath))

Workbook wb = WorkbookFactory.create(fis)
Sheet sh = wb.getSheet(sheetName)

Iterator itrRow = sh.rowIterator()
while(itrRow.hasNext())
{
    Row row = itrRow.next()
    for(Cell cell : row)
    {
        switch(cell.getCellType())
        {
            case Cell.CELL_TYPE_NUMERIC:
                log.info cell.getNumericCellValue()
                break;
            default:
                log.info cell.getRichStringCellValue()
        }      
    }  
}

fis.close()
wb.close()

In Ready API 2.8.0 show me the error but in SOAPUI 5.2.1 does not show error

I´ve put the flowing libraries in ReadyAPI 2.8.0

poi-4.1.1.jar

poi-excelant-4.1.1.jar

poi-ooxml-4.1.1.jar

poi-ooxml-schemas-4.1.1.jar

poi-scratchpad-4.1.1.jar

Could be any library incompatible with READY APi2.8.0?
