InvalidClassException

public class InvalidClassException extends ObjectStreamException
Signals a problem during the serialization or or deserialization of an object. Possible reasons include:
  • The SUIDs of the class loaded by the VM and the serialized class info do not match.
  • A serializable or externalizable object cannot be instantiated (when deserializing) because the no-arg constructor that needs to be run is not visible or fails.
