             Summary: CLONE - Unable to deserialize Vector when using JDK 7
                 Key: JBSER-129
                 URL: https://issues.jboss.org/browse/JBSER-129
             Project: JBoss Serialization
          Issue Type: Bug
    Affects Versions: 1.0.5.FINAL
         Environment: JBoss EAP 5.2 on JDK 7
            Reporter: Brad Maxwell
            Assignee: Brad Maxwell


JDK 7 changed the writeObject of Vector, 

ObjectOutputStreamProxy.writeFields is being called, which write the fields out not as a FinalContainer , writeMyself checks the type and for non FinalContainer it just writes the object in metho FieldsContainer.writeField as:

            out.writeByte(DataContainerConstants.OBJECTREF);
            out.writeObject(value);

When reading, RegularObjectPersister is expecting all FinalContainer.

So it looks like either FinalContainer.writeField may need to wrap the objects in a FinalContainer or on the reading side it needs to read the non wrapped fields before reading the wrapped fields.


public void writeFields() throws IOException {
        if (currentContainer!=null)
        {
            currentContainer.writeMyself(this);
            currentContainer=null;
        }


JDK 6
--------------------------------------------------------------------------
public class Vector<E>
    extends AbstractList<E>

    private synchronized void writeObject(java.io.ObjectOutputStream s)
        throws java.io.IOException
    {
  s.defaultWriteObject();
    }


JDK 7
--------------------------------------------------------------------------
    private void writeObject(java.io.ObjectOutputStream s)
            throws java.io.IOException {
        final java.io.ObjectOutputStream.PutField fields = s.putFields();
        final Object[] data;
        synchronized (this) {
            fields.put("capacityIncrement", capacityIncrement);
            fields.put("elementCount", elementCount);
            data = elementData.clone();
        }
        fields.put("elementData", data);
        s.writeFields();
    }
