The method readObject of class java.beans.XMLDecoder
throws undocumented ArrayIndexOutOfBoundsException
if object is not writen to stream by XMLEncoder.

Here is minimized test:
import java.io.ByteArrayOutputStream;
import java.io.ByteArrayInputStream;
import java.beans.XMLEncoder;
import java.beans.XMLDecoder;

public class Test0004 {

    public static void main(String[] args) {
        ByteArrayOutputStream os = new ByteArrayOutputStream();
        XMLEncoder xmlEnc = new XMLEncoder(os);
        xmlEnc.flush();
        ByteArrayInputStream in = new ByteArrayInputStream(os.toByteArray());
        XMLDecoder xmlDec = new XMLDecoder(in);

        Object res = xmlDec.readObject();
    }
}
