There are two parts in the attachment uploaded.
1. A sample with a excel file(.xlsx format) and a java source.
2. A modified source(org.apache.poi.ss.formula.FormulaShifter.java) to resolve
the problem.

It will be helpful if whether the problem is truely existing and whether the
modified is OK are confirmed ASAP.
Thank you.
