Did you read my edit which spoke of doing some simple debugging? I am working too hard for those dukes by the way. So far you haven't even said "thank you for trying" at all. (And no, I'm not really working for them. They're worthless. But at least a "thank you" of some type is in order!)

6. NumberFormatException with too long numbers using eval() BeanShell method    forums.oracle.com

I've a problem using Interpreter BeanShell class. When the interpreter tries to evaluate a formula (ie: ((3000000000 + 18)*10), as some of the numbers are bigger than an "int" value the method returns a NumberFormatException. So I don't really know how to evaluate this kind of situation. Any suggestion?. Thanks a million for your help. RNM.

9. NumberFormatException plz help...    forums.oracle.com

So do you have the source code or not? If you do, find where the exception is being thrown from. It's most likely caused by trying to parse a number out of a String that doesn't contain a number. Figure out how the String you are trying to parse could contain a non-number, and reproduce that.
