Doc from java.io.ObjectInputStream.resolveClass.

Load the local class equivalent of the specified stream class description. Subclasses may implement this method to allow classes to be fetched from an alternate source.

The corresponding method in ObjectOutputStream is annotateClass. This method will be invoked only once for each unique class in the stream. This method can be implemented by subclasses to use an alternate loading mechanism but must return a Class object. Once returned, if the class is not an array class, its serialVersionUID is compared to the serialVersionUID of the serialized class, and if there is a mismatch, the deserialization fails and an InvalidClassException is thrown.

The default implementation of this method in ObjectInputStream returns the result of calling

Class.forName(desc.getName(), false, loader) 
Class.forName(desc.getName(), false, loader)
where loader is the first class loader on the current thread's stack (starting from the currently executing method) that is neither the platform class loader nor its ancestor; otherwise, loader is the platform class loader. If this call results in a ClassNotFoundException and the name of the passed ObjectStreamClass instance is the Java language keyword for a primitive type or void, then the Class object representing that primitive type or void will be returned (e.g., an ObjectStreamClass with the name "int" will be resolved to Integer.TYPE). Otherwise, the ClassNotFoundException will be thrown to the caller of this method.
Parameters
v:ObjectStreamClass

an instance of class ObjectStreamClass

Returns:Class<?>

a Class object corresponding to desc

Exceptions
IOException:
any of the usual Input/Output exceptions.
ClassNotFoundException:
if class of a serialized object cannot be found.
