csFirstRow.setFillPattern(CellStyle.SOLID_FOREGROUND);

    It seems to be unnessecary to set the Fill Background. It requires the “fillPattern”

    csFirstRow.setFillForegroundColor(HSSFColor.GREY_25_PERCENT.index);
csFirstRow.setFillPattern(CellStyle.SOLID_FOREGROUND);

    as javadoc says (setFillPattern)

    setting to one fills the cell with the foreground color… No idea about other values

    Now it works as it should

    thanks to this helpfull answer on stackoverflow
