I just used ior-decode to verify that the object key is equal.

I have an interface as parameter in the call that produces this error. BTW, the
warning occures twice, and I have now found, that a method call to a function
of the interface fails. The details:

IDL contains:

        ...
        interface ServerCB
        {
            oneway void handleEvent(in Events events );
        };
        ...
        interface Device
        {
            void register_event_callback ( in ServerCB eventCB )
                raises ( thema::TheMaException );
        }

For interface ServerCB, ORBit is client, for interface Device, ORBit is server.
The error occures, if register_event_callback() is invoked by the JacORB client.

Then a following call to handleEvent produces a JacORB exception:

[ POA TheMaRegistration - rid: 2147481680 oid: ServerCB-1008768501906 opname:
handleEvent - invocation: system exception was thrown
(org.omg.CORBA.BAD_OPERATION: handleEvent not found  vmcid: 0x0  minor code: 0 
completed: No) ]

I'm not sure wether this JacORB exception is caused by the preceding ORBit
warning (error). What do you think? I do not know, what consequences the error
ORBit internally has.

It is fixed. Cause I crosscompile to powerpc, I have to set the alignments by
hand (configure does not work on that topic if crosscompiling) and handwork is
faulty ;-)
