35/**
36 * The Indirection exception is a Java specific system exception.
37 * It is thrown when the ORB's input stream is called to demarshal
38 * a value that is encoded as an indirection that is in the process
39 * of being demarshaled. This can occur when the ORB input stream
40 * calls the ValueHandler to demarshal an RMI value whose state
41 * contains a recursive reference to itself. Because the top-level
42 * ValueHandler.read_value() call has not yet returned a value,
43 * the ORB input stream's indirection table does not contain an entry
44 * for an object with the stream offset specified by the indirection
45 * tag. The stream offset is returned in the exception's offset field.
46 * @see org.omg.CORBA_2_3.portable.InputStream
47 * @see org.omg.CORBA_2_3.portable.OutputStream
