/** 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.
  *
  * <P>If a collection of Java objects must be sent, one of the 
  * {@code Collection} classes provided since JDK 1.2 can be used.
  *
  * <P>When a client receives an {@code ObjectMessage}, it is in read-only 
  * 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.
