/**
* Deserializes an {@link MBeanFeatureInfo} from an {@link ObjectInputStream}.
*
* @serialData For compatibility reasons, an object of this class is deserialized as follows.
* <ul>
* The method {@link ObjectInputStream#defaultReadObject defaultReadObject()} is called
* first to deserialize the object except the field {@code descriptor}, which is not
* serialized in the default way. Then the method {@link ObjectInputStream#read read()} is
* called to read a byte, the field {@code descriptor} is deserialized according to the
* value of the byte value:
* <ul>
* <li>1. The method {@link ObjectInputStream#readObject readObject()} is called twice to
* obtain the field names (a {@code String[]}) and the field values (a {@code
* Object[]}) of the {@code descriptor}. The two obtained values then are used to
* construct an {@link ImmutableDescriptor} instance for the field {@code descriptor};
* <li>0. The value for the field {@code descriptor} is obtained directly by calling the
* method {@link ObjectInputStream#readObject readObject()}. If the obtained value is
* null, the field {@code descriptor} is set to {@link
* ImmutableDescriptor#EMPTY_DESCRIPTOR EMPTY_DESCRIPTOR};
* <li>-1. This means that there is no byte to read and that the object is from an earlier
* version of the JMX API. The field {@code descriptor} is set to {@link
* ImmutableDescriptor#EMPTY_DESCRIPTOR EMPTY_DESCRIPTOR}
* <li>Any other value. A {@link StreamCorruptedException} is thrown.
* </ul>
* </ul>
