NumberFormat.getPercentInstance() does not work correctly for a double
value. The attached test works fine with jdk 1.4.2.
Platform


import java.text.*;
import java.util.*;

public class Test {
    public static void main(String [] args) {
        NumberFormat fmt = NumberFormat.getPercentInstance();

        Test tt = new Test();
        tt.doTest(fmt, new Double(9223372036854775808.0));
        tt.doTest(fmt, new Double(-9223372036854775809.0));
    }

    public void doTest(NumberFormat fmt, Number value) {
        String s = fmt.format(value);
        String s2 = null;
        Number n = null;

        try {
            n = fmt.parse(s);
            s2 = fmt.format(n);

            if (!s.equals(s2)) {
               System.out.println("s is " + s);
               System.out.println("s2 is " + s2);
               System.out.println("FAIL");
            }
        } catch (Exception e) {
           e.printStackTrace();
        }
    }
}

Output:
--------
s is 922,337,203,685,477,600,000%
s2 is 922,337,203,685,477,580,700%
FAIL

s2 is -922,337,203,685,477,580,800%
