/** An {@code ObjectMessage} object is used to send a message that contains
* a serializable object in the Java programming language ("Java object").
* It inherits from the {@code Message} interface and adds a body
* containing a single reference to an object. Only {@code Serializable}
* Java objects can be used.
*
* If a collection of Java objects must be sent, one of the
* {@code Collection} classes provided since JDK 1.2 can be used.

* mode. If a client attempts to write to the message at this point, a
* {@code MessageNotWriteableException} is thrown. If
* {@code clearBody} is called, the message can now be both read from and
* written to.
