  23.  * The Indirection exception is a Java specific system exception. 

  24.  * It is thrown when the ORB's input stream is called to demarshal 

  25.  * a value that is encoded as an indirection that is in the process 

  26.  * of being demarshaled. This can occur when the ORB input stream 

  27.  * calls the ValueHandler to demarshal an RMI value whose state 

  28.  * contains a recursive reference to itself. Because the top-level 

  29.  * ValueHandler.read_value() call has not yet returned a value, 

  30.  * the ORB input stream's indirection table does not contain an entry 

  31.  * for an object with the stream offset specified by the indirection 

  32.  * tag. The stream offset is returned in the exception's offset field.
