+title: 'Java Object Serialization Specification: B - Exceptions In Object Serialization'
+---
+
+-------------------------------------------------------------------------------
+
+All exceptions thrown by serialization classes are subclasses of
+`ObjectStreamException` which is a subclass of `IOException`.
+
+### `ObjectStreamException`
+
+Superclass of all serialization exceptions.
+
+### `InvalidClassException`
+
+Thrown when a class cannot be used to restore objects for any of these reasons:
+
+-   The class does not match the serial version of the class in the stream.
+-   The class contains fields with invalid primitive data types.
+-   The `Externalizable` class does not have a public no-arg constructor.
+-   The `Serializable` class can not access the no-arg constructor of its
+    closest non-Serializable superclass.
+
+### `NotSerializableException`
+
+Thrown by a `readObject` or `writeObject` method to terminate serialization or
+deserialization.
+
+### `StreamCorruptedException`
+
+Thrown:
+
+-   If the stream header is invalid.
+-   If control information not found.
+-   If control information is invalid.
+-   JDK 1.1.5 or less attempts to call `readExternal` on a `PROTOCOL_VERSION_2`
+    stream.
+
+### `NotActiveException`
+
+Thrown if `writeObject` state is invalid within the following
+`ObjectOutputStream` methods:
+
+-   `defaultWriteObject`
+-   `putFields`
+-   `writeFields`
+
+Thrown if `readObject` state is invalid within the following
+`ObjectInputStream` methods:
+
+-   `defaultReadObject`
+-   `readFields`
+-   `registerValidation`
+
+### `InvalidObjectException`
+
+Thrown when a restored object cannot be made valid.
+
+### `OptionalDataException`
+
+Thrown by `readObject` when there is primitive data in the stream and an object
+is expected. The length field of the exception indicates the number of bytes
+that are available in the current block.
+
+### `WriteAbortedException`
+
+Thrown when reading a stream terminated by an exception that occurred while the
+stream was being written.
