/**
* Implementation class that uses Java serialization for input streams.
* This assumes a GIOP version 1.2 message format.
*
* This class uses a ByteArrayInputStream as the underlying buffer. The
* first 16 bytes are directly read out of the underlying buffer. This allows
* [GIOPHeader (12 bytes) + requestID (4 bytes)] to be read as bytes.
* Subsequent write operations on this output stream object uses
* ObjectInputStream class to read into the buffer. This allows unmarshaling
* complex types and graphs using the ObjectInputStream implementation.
*
* Note, this class assumes a GIOP 1.2 style header. Further, the first
* 12 bytes, that is, the GIOPHeader is read directly from the received
* message, before this stream object is called. So, this class effectively
* reads only the requestID (4 bytes) directly, and uses the
* ObjectInputStream for further unmarshaling.
