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