* <li>An attempt was made to read an object when the next element in the

* stream is primitive data. In this case, the OptionalDataException's

* length field is set to the number of bytes of primitive data
|
|
* immediately readable from the stream, and the eof field is set to
|
|
* false.
|
|
*
|
|
* <li>An attempt was made to read past the end of data consumable by a
|
|
* class-defined readObject or readExternal method. In this case, the
|
|
* OptionalDataException's eof field is set to true, and the length field
|
|
* is set to 0.
