/**
 * Deserializes an {@link MBeanInfo} from an {@link ObjectInputStream}.
 * @serialData
 * For compatibility reasons, an object of this class is deserialized as follows.
 * <p>
 * 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>
 *    <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>
 *    <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>
 *    <li>Any other value. A {@link StreamCorruptedException} is thrown.</li>
 *    </ul>
