Description Kai Zimmermann 2010-01-02 05:52:02 UTC 
When I use OperandResolver.parseDouble to parse a string like excel and I write 

OperandResolver.parseDouble("-");

 then occurs the following bug:

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 0
	at java.lang.String.charAt(Unknown Source)
	at org.apache.poi.hssf.record.formula.eval.OperandResolver.parseDouble(OperandResolver.java:247)



PS: I know this will never use by anybody in this way, but if we calculate a formula with a reference to a minus, then occur exactly this, because the formulae use also OperandResolver.parseDouble
