/**
* Implementation class that uses Java serialization for output streams.
* This assumes a GIOP version 1.2 message format.
*
* This class uses a ByteArrayOutputStream as the underlying buffer. The
* first 16 bytes are direct writes into the underlying buffer. This allows
* [GIOPHeader (12 bytes) + requestID (4 bytes)] to be written as bytes.
* Subsequent write operations on this output stream object uses
* ObjectOutputStream class to write into the buffer. This allows marshaling
* complex types and graphs using the ObjectOutputStream implementation.
*
* Note, this class assumes a GIOP 1.2 style header. Note, we expect that the
* first 16 bytes are written only using the write_octet, write_long or
* write_ulong method calls.
