      Description

      There is a bug in the java orb such that we are unable to have a ORBit2 (gnome-2.0) client invoke a java method on a Java Object.
      I've attached the source files I've been using, its a simple test program that
      illustrates the problem.


      Running the simple Java "Hello World" server , the ORBit2 client tries to call method defined in the IDL. However a BAD_OPERATION( when using java1.4) / DATA_CONVERSION (java 1.3) exception occurs.

      Below is a printout of the request from the ORBit client and the reply
      it recieves from the Java ORB

      Basically the Java ORB returns an incorrect value for the endian-ness
      (byte order) of the data that it returns in response to a CORBA IIOP
      request.

      Here's the request orbit sends. The first line of each message is the
      header.

      Outgoing IIOP data:
      0x 0 47 49 4f 50 1 1 1 0 54 0 0 0 XX XX XX XX |GIOP....T...**** ---
                               ^^^ ^^^^^^^^^^^

                          1 indicates little encoded little
                            endian endian

      And ORBit fails to decode the reply


      This bug appears using 1.4.0-beta2, 1.3.1_01 and jdk1.2.2_07 on both linux and solaris.

      There is no workaround, so until this is fixed, we are blocked on a
      Sun strategic project impacting the Solaris desktop and the use of Java on Solaris and Linux. This bug makes it impossible to deliver Java Accessibility on Solaris.
