  THE IBM Java Development Kit does not serialize XML
  correctly.  The following sample code demonstrates the
  problem:
  
  import java.beans.XMLEncoder;
  import java.io.ByteArrayOutputStream;
  
  public class XMLSerializeEnumTest {
  
  
     public static enum Animal { Dog, Cat, Bear; }
  
     public static class Bean {
        private Animal animal;
        public Animal getAnimal() { return animal; }
        public void setAnimal(Animal animal) { this.animal =
  animal; }
     }
  
     public static void main(String[] args) {
        Bean bean = new Bean();
        bean.setAnimal(Animal.Cat);
        ByteArrayOutputStream baos = new
  ByteArrayOutputStream();
        XMLEncoder xmlEncoder = new XMLEncoder(baos);
        xmlEncoder.writeObject(bean);
        xmlEncoder.close();
        System.out.println(new String(baos.toByteArray()));
     }
  }
  
  This will result in the following output:
  
  Exception during encoding:java.lang.Exception: failed to
  write expression: XMLSerializeEnumTest$Animal=Class.new();
  
  Continue...
  Exception during encoding:java.lang.Exception: failed to
  write expression: XMLSerializeEnumTest$Animal=Class.new();
  
  Continue...
  
  ??xml version="1.0" encoding="UTF-8"??
  ?java version="1.6.0" class="java.beans.XMLDecoder"?
     ?object class="XMLSerializeEnumTest$Bean"/?
  ?/java?
  

Problem conclusion

• The IBM Java Development Kit has been updated to Java 6 SR9
  which includes the fix for APAR IZ92409.
  
  The fix for this APAR will be included in Rational
  Application Developer version 8.0.2.
