java.text.DecimalFormat.format(double n, StringBuffer str, FieldPosition fp) formats
wrong if `Math.pow(10, getMaximumFractionDigits()) * n' greater than Long.MAX_VALUE or
less than Long.MIN_VALUE.
 
Here is the test demonstrating the bug:

-----------------Test.java------------------------
import java.text.*;

public class Test {
    public static void main (String args[]){
        DecimalFormat df = new DecimalFormat();
        double d = 100;
        df.setMinimumFractionDigits(0);
        df.setMaximumFractionDigits(16);
        StringBuffer sBuf1 = new StringBuffer("");
        FieldPosition fp1 = new FieldPosition(0);
        System.out.println("d = " + d);
        System.out.println("maxFractionDigits = " + df.getMaximumFractionDigits());
        System.out.println(" format(d) = '" + df.format(d, sBuf1, fp1) + "'");
        System.out.println();
        df.setMaximumFractionDigits(17);
        StringBuffer sBuf2 = new StringBuffer("");
        FieldPosition fp2 = new FieldPosition(0);
        System.out.println("maxFractionDigits = " + df.getMaximumFractionDigits());
        System.out.println(" format(d) = '" + df.format(d, sBuf2, fp2) + "'");
    }
}
---------Output from the test---------------------
d = 100.0
maxFractionDigits = 16
  format(d) = '100'
 
maxFractionDigits = 17
  format(d) = '92.23372036854775807'
