If all the objects within the bean implement Serializable
interface, will BeanUtils.cloneBean()
do a deep copy?

Use SerializationUtils.clone method from the Apache Commons Lang for the deep copy. It copies the entire class hierarchy.
SerializationUtils.clone(object);
There is also another java library which supports both shallow cloning and deep cloning. It offers deep cloning without the need to implement Serializable.
