small factorial(shows runtime error! while runs fine in my machine)

import java.io.*;
import java.math.BigInteger;

public class small {
    public static final int MAX_SIZE = 100;

    public static BigInteger factorial( final int n ) {
        BigInteger result = BigInteger.ONE;
        if ( n == 0 ) {
            return BigInteger.ONE;
        } else {
            result = new BigInteger( "" + n ).multiply( factorial( n - 1 ) );
            return result;
        }
    }

    public static void main( final String[] args ) throws IOException {
        final BufferedReader br = new BufferedReader( new InputStreamReader( System.in ) );
        final int m = Integer.parseInt( br.readLine() );
        while ( m > 0 && m <= MAX_SIZE ) {

            final int n = Integer.parseInt( br.readLine() );
            if ( n <= MAX_SIZE ) {
                System.out.println( factorial( n ) );
            }
        }
    }
}

Did you find the problem? I saw your AC submission.
