[attachment : files.zip]
ok.xlsx : D1-D12 has formula
ng.xlsx : D1-D12 has shared formula

A result file[result_ng.xlsx] has break formula.
Open and Rescue by Excel, cells[D11-D12] formula is gone.

The setCellFormula method can not clear formula like this.
(*Exclude the case where only D1 is cleared.)
 <c r="D1" s="2">
  <f t="shared" ref="D1:D12" si="0">B1*C1</f>

Test code.

public static void test() {

public static void formulaTest(String file) {
  ConditionalFormattingTest test = new ConditionalFormattingTest(file);
  XSSFSheet sheet = (XSSFSheet)test.getSheet(0);		
  for (int i=0; i<10; i++) {
  test.writeBook("result_" + file);
