Henri Yandell updated BEANUTILS-281:
------------------------------------

    Fix Version/s: LATER THAN 1.8.0

I doubt we'll do anything about this in 1.8.0 as covariant return types are a 
JDK 1.5 feature and I'm sure 1.8.0 won't be 1.5 dependent. It's possible the 
feature could be added without using 1.5, but I suspect the code requiring 
change would turn out to be in java.beans.

> BeanUtils.cloneBean and Covariant (Overriding) return types

> BeanUtils.cloneBean(Object) method does not copy the fields that are 
> overriden by the subclasses. For example, consider an abstract 
> class(AbstractVehicle) where you define an abstract getter for a field. 
> **************************
> public abstract class AbstractVehicle {
>       public abstract Serializable getField();
> }
> ***************************
> In a class (Car) that extends this abstract class (AbstractVehicle) you 
> define the field itself and override the return type of the getter method 
> (from Serializable to Integer):
> ***************************
> public class Car extends AbstractVehicle {
>       private Integer field = null;
>       @Override
>       public Integer getField() {
>               return field;
>       }
>       public void setField(Integer field) {
>               this.field = field;
>       }
> }
> ***************************
> When you clone such objects (Car) this field is not copied! The following 
> code prints 'null' instead of 5!
> ***************************
> public class CopyTestMain {
>       public static void main(String[] args) throws IllegalAccessException, 
> InstantiationException, InvocationTargetException, NoSuchMethodException {
>               final Car aCar = new Car();
>               aCar.setField(5);
>               final Car copyCar = (Car) BeanUtils.cloneBean(aCar);
>               System.out.println("Field = " + copyCar.getField());
>       }
> }
> ***************************
