20  * The Indirection exception is a Java specific system exception.
21  * It is thrown when the ORB's input stream is called to demarshal
22  * a value that is encoded as an indirection that is in the process
23  * of being demarshaled. This can occur when the ORB input stream
24  * calls the ValueHandler to demarshal an RMI value whose state
25  * contains a recursive reference to itself. Because the top-level
26  * ValueHandler.read_value() call has not yet returned a value,
27  * the ORB input stream's indirection table does not contain an entry
28  * for an object with the stream offset specified by the indirection
29  * tag. The stream offset is returned in the exception's offset field.
