DecimalFormatter.format(object) gives strange results on i5 JVM 1.4 Classic

When I run the following in WDSC and netbeans I get the result I would
expect. However when I run it on the i5 JVM 1.4 I get an unexpected result.
I'm probably missing something really obvious, any help would be
appreciated.



public static void main(String[] args) {



BigDecimal num = new BigDecimal("123456789987654321123456789987");

DecimalFormat df = new DecimalFormat();

df.setMaximumFractionDigits(99);

df.setMaximumIntegerDigits(99);

df.setMinimumFractionDigits(3);

df.setMinimumIntegerDigits(3);



df.setGroupingUsed(true);

df.setGroupingSize(3);



String s = df.format(num);



System.out.println(s);





}



Result in WDSC and Netbeans s =
"123,456,789,987,654,321,123,456,789,987.000"



Result when run on i5 s = "123,456,789,987,654,321,123,300,000,000.000"



Thanks for taking a look.
