Method
protected void flush() of class java.beans.XMLEncoder
throws NullPointerException if java.math.BigInteger and java.math.BigDecimal
have been writen to output stream before.

Here is minimized test:
import java.io.*;
import java.beans.*;
import java.math.*;

public class Test0008 {

    public static void main(String[] args) {
        ByteArrayOutputStream os = new ByteArrayOutputStream();
        Object[] objects = {BigInteger.ONE, new BigDecimal(BigInteger.ONE)};
        XMLEncoder xmlEnc = new XMLEncoder(os);
        for (int i = 0; i < objects.length; i++) {
            xmlEnc.writeObject(objects[i]);
        }
        xmlEnc.flush();
        xmlEnc.close();
        ByteArrayInputStream in = new ByteArrayInputStream(os.toByteArray());
        XMLDecoder xmlDec = new XMLDecoder(in);
                System.out.println("OutputStream");
                System.out.println(os.toString());
        for (int i = 0; i < objects.length; i++) {
            Object res = xmlDec.readObject();
            if (!objects[i].equals(res)) {
                System.out.println("FAILED");
                System.out.println("Object type: " + objects[i].getClass());
                System.out.println("Result : " + res);
                System.out.println("Expected: " + objects[i]);
            }
        }
    }
