Description Eric Ladner 2002-07-12 12:59:52 UTC
Under some conditions, the parser will attempt to step off the end of the string
and get an index out of bounds.  This just adds a check to getChar that won't
allow getCharAt to return something for a pointer that's byond the end of the

Also uncommented Multiply and Divide in Expression.  They seem to work correctly.

Thank you kindly for this patch.  In the future please don't forget to add
yourself to the "@author" tags.  We like to share credit!  :-)

As just a humbe suggestion, it might be useful to create a unit test (new method
off of src/testcases/org/apache/poi/hssf/model/TestFormulaParser) that
demontrates teh bug so that it doesn't break again later.

applied, please crosscheck.
