How new objects are instantiated when reading from object stream?

Question

Hi,
How the serializable API instantiates new objects when reading from stream?
First it needs to create a new instance of a class and then fill its' fields with a serialized data. But not all serializable classes have empty constructor (as it have java beans) to make simple call of Class.newInstance(). Is there any way to create a virgin instance of any class?

I found the way, but it is not a solution:
Constructor serializableConstructor = sun.reflect.ReflectionFactory.getReflectionFactory().newConstructorForSerialization( Class instanceClass, Constructor superClassEmptyConstructor );
Object obj = serializableConstructor.newInstance();This "magic" method creates an empty constructor for a serializable class from empty constructor of any superclass. The limitation is that a first non-serializable superclass must have an empty constructor.
As this magic method locates in a package sun.** I think this will not work with other JREs.
