    1.31 + * Exception indicating the failure of an object read operation due to
    1.32 + * unread primitive data, or the end of data belonging to a serialized
    1.33 + * object in the stream.  This exception may be thrown in two cases:
    1.34 + *
    1.35 + * <ul>
    1.36 + *   <li>An attempt was made to read an object when the next element in the
    1.37 + *       stream is primitive data.  In this case, the OptionalDataException's
    1.38 + *       length field is set to the number of bytes of primitive data
    1.39 + *       immediately readable from the stream, and the eof field is set to
    1.40 + *       false.
    1.41 + *
    1.42 + *   <li>An attempt was made to read past the end of data consumable by a
    1.43 + *       class-defined readObject or readExternal method.  In this case, the
    1.44 + *       OptionalDataException's eof field is set to true, and the length field
    1.45 + *       is set to 0.
