Returns the first non-serializable superclass of a given class. According to Java Object
Serialization Specification, objects read from a stream are initialized by calling an
accessible no-arg constructor from the first non-serializable superclass in the object's
hierarchy, allowing the state of non-serializable fields to be correctly initialized.

@param <T> Type to instantiate
@param type Serializable class for which the first non-serializable superclass is to be found
@return The first non-serializable superclass of 'type'.
