Hello All
       I want create a xls workbook that the sheets number are greater than 64 
and every sheet has comment, it work at the version 3.10, but it not work at 
3.12 and later version. The following code is my test code. The first 63 sheets 
is ok, but when the sheets are greater than 64 , it throw the exception "The 
exception is Cannot add more than 65535 shapes. "

import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFClientAnchor;
import org.apache.poi.hssf.usermodel.HSSFComment;
import org.apache.poi.hssf.usermodel.HSSFPatriarch;
import org.apache.poi.hssf.usermodel.HSSFRichTextString;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class CellComments {

  public static void main(String[] args) {
    HSSFWorkbook wb = new HSSFWorkbook();
    for (int i = 0; i < 256; i++) {
      HSSFSheet sheet = wb.createSheet("Cell comments in POI HSSF" + (i + 1));
      // Create the drawing patriarch. This is the top level container for all 
shapes including cell comments.
      HSSFPatriarch patr = sheet.createDrawingPatriarch();
      try {
        //create a cell in row 3
        HSSFCell cell = sheet.createRow(0).createCell(0);
        cell.setCellValue(new HSSFRichTextString("Hello, World"));
        //anchor defines size and position of the comment in worksheet
        HSSFComment comment = patr.createComment(new HSSFClientAnchor(0, 0, 0, 
0, (short) 1,  1, (short) 6, 4));
        // set text in the comment
        comment.setString(new HSSFRichTextString("We can set comments in POI" + 
0));
        //set comment author.
        //you can see it in the status bar when moving mouse over the commented 
cell
        comment.setAuthor("Apache Software Foundation");
        // The first way to assign comment to a cell is via 
HSSFCell.setCellComment method
        cell.setCellComment(comment);
      } catch (Exception e) {
        System.out.printf("Add comment fail at sheet%d. The exception is %s%n", 
i+1, e.getMessage());
      }
    }
    try (FileOutputStream out = new FileOutputStream("poi_comment.xls")) {
      wb.write(out);
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

   I have checked the bug list. At the 3.12 version,  to fix the bug 56380, 
added the following code. The bug of 56380 is fixed, but when the sheet number 
is greater than 64, the sharpId will greater than 65535.
