DecimalFormat incorrectly formats BigDecimals.
Here is a small Program:

import java.math.BigDecimal;
import java.text.*;
import java.util.Locale;
public class DecimalFormatTest {
  public static void main(String[] args) {
    DecimalFormat format =
        (DecimalFormat)NumberFormat.getInstance(Locale.GERMANY);
    StringBuffer buf = new StringBuffer(30);
    format.format(new BigDecimal("9876543210987654321"),buf,new
        FieldPosition(0));
// format.format(new BigDecimal("987654321098765432"),buf,new
        FieldPosition(0));
// format.format(new BigDecimal("98765432109876543"),buf,new FieldPosition(0));
// format.format(new BigDecimal("9876543210987653"),buf,new FieldPosition(0));
    System.out.println(buf);
  }
}

Try any of the formattings, each is wrong.
Output first value: 9.876.543.210.987.655.000
Output second value: 987.654.321.098.765.440
Output third value: 98.765.432.109.876.544
Output fourth value: 9.876.543.210.987.652

Formatting large double values with java.text.FormatDecimal changes the value
that should be formatted. (see Screenshot).
Formatting is done by

  void input_focusLost(FocusEvent e) {
    DecimalFormatSymbols symbols = new DecimalFormatSymbols();
    DecimalFormat decForm = new DecimalFormat("###,###,###.00", symbols);
    output.setText(decForm.format( new Float(input.getText()).floatValue()));
  }

if you enter:
'666333999000' the result is
666,334,003,200.00
