Bug ID: 58648
Summary: FormulaParser throws exception in parseSimpleFactor()
when getCellFormula() is called on a cell and the
formula contains spaces between closing parentheses ")
)"
Product: POI
Version: 3.13-FINAL
Hardware: PC
Status: NEW
Severity: critical
Priority: P2
Component: SS Common
Assignee: dev@poi.apache.org
Reporter: apa...@rpdavison.ca
To reproduce:
Define an XSSFCell with a formula like: "((1 + 1) )".
Note the extra space between the closing parentheses.
Or create a spreadsheet with a cell with the formula specified above, save it
and then read it in as a workbook. Navigate via POI to the sheet, row, and
cell in question.
Call getCellFormula() on the cell.
Results in an exception:
org.apache.poi.ss.formula.FormulaParseException: Parse error near char ... ')'
in specified formula '((1 + 1) )'. Expected cell ref or constant literal

Remove the white space between the two closing parentheses and the exception
goes away.
Proposed fix:
Add an additional call to "SkipWhite()" before the call to "Match(')');" inside
the case for '('. Near line 1130 in parseSimpleFactor method of
FormulaParser.java (release version 3.13).
