Large amount was truncated when format by decimalformat

I using the following method to display amount, but it is truncated for large amount.

public static void main(String[] args) {

DecimalFormat decimalFormat = new DecimalFormat();

decimalFormat.applyPattern("#,###.000");

BigDecimal bigDecimal = new BigDecimal("400000017202222222222");

bigDecimal = bigDecimal.movePointLeft(3);

System.out.println(decimalFormat.format(bigDecimal));

//System.out.println(bigDecimal);

}
